Analyze Data

The Graph is the foundation for exploring data in Graphext. It contains a visual representation of your data points often grouped together into clusters. The position of your points - or nodes - on the Graph represents their relationship to one another. The nature and strength of their connections is defined by the recipe you create.

Use the Graph to begin investigating patterns in your dataset. You can customise its appearance, zoom in and examine specific groups or take a snapshot of it's layout and save it as an insight.

"Mankind invented a system to cope with the fact that we are so intrinsically lousy at manipulating numbers. It's called the graph."

- Charlie Munger

Nodes and Links

A node is a junction on the Graph representing one of your data points. Every row in your dataset is represented by a node and plotted on the Graph. The position of a node is defined by its features and their connection to the features of other nodes. These relationships are represented as links between nodes.

Node Size Mapping

Use quantitative variables to add a size dimension to your Graph. Data points with a higher value for a set variable will be represented as larger nodes in your Graph. You can set a default value for your node sizes in your project's settings.

The larger a node is, the higher the value it has for a set variable.

How to Apply Size Mapping?

  1. Start from your project's Graph.
  2. From the right or left sidebar, locate the quantitative variable you want to map the size of.
  3. Select the size mapping icon next to the variable name - smaller circles inside of a larger circle.
  4. Done ... The nodes on your Graph have resized to represent their value for this variable.

Setting Region Labels

Regions are areas of your Graph defined by the presence of a number of values within a variable. Regions can be defined by any variable in your data. When you set region labels, the names of values featured within that variable will appear in your Graph over the areas featuring groups of data points with that value.

Change the variable representing your region labels using the project settings window.

How to Set Region Labels?

  1. Start from your project's Graph.
  2. Select the icon representing your project settings from the top of the Graph window - a cog.
  3. Under 'Labels', select the dropdown menu associated with region labels.
  4. Select a new column from the menu list.
  5. Select 'Save'.
  6. Done ...  The regions of your Graph are now represented by the names of values from the variable you have selected.

Setting Node Labels

Labels are the text that appears over nodes. They show a node's value for a particular variable. You can change what variable a label represents in your project settings.

When you search for data in the Graph, your query is matched against node labels.

How to Set Node Labels?

  1. Start from your project's Graph.
  2. Select the icon representing your project settings from the top of the Graph window - a cog.
  3. Under 'Labels', select the dropdown menu associated with node labels.
  4. Select a new column from the menu list.
  5. Select 'Save'.
  6. Done ... Your nodes are labelled with their values belonging to the variable you have just selected.

Setting Label Density

Adjusting the density of labels will change how many node labels appear. Zooming into the Graph makes more labels appear.

They show a node's value for a particular variable. Adjusting the density of labels will change how many node labels appear.

How to Set Label Density?

  1. Start from your project's Graph.
  2. From the top of the Graph window, select the icon representing node labels - a tag.
  3. Drag the slider left and right to adjust the density of labels in the Graph.
  4. Labels in the Graph will respond immediately.
  5. Done ... The density of your labels now reflects the changes you made.

Hiding Node Links

Links between nodes represent the connection between rows in your dataset. Links define a node's position by pulling it towards nodes with similar features and therefore creating clusters. Hiding node links can sometimes create a cleaner aesthetic inside your Graph and allow for easier recognition of smaller clusters.

The position of nodes in the Graph was defined in the setup of your project. Hiding the links between nodes won't change their position.

How to Hide Node Links?

  1. Start from your project's Graph.
  2. Select the icon representing your project settings from the top of the Graph window - a cog.
  3. Under 'Connections', untick the checkbox 'Show node connections'.
  4. Select 'Save'.
  5. Done ... The links between your nodes have been hidden.

Node Color Mapping

Color is an immediately recognisable feature of design distinguishing one group from another. Colour mapping is a powerful way to signal the difference between different groups in your data. Using the variable charts in the left and right sidebars you can apply colour mapping to any feature of your dataset.

Emphasize data groups by applying colour mapping to new segmentations that you create. This also changes the color of your node links.

How to Apply Colour Mapping?

  1. Start from your project's Graph.
  2. From the right or left sidebar, locate the variable you want to map the colour of.
  3. Select the colour mapping icon next to the variable name - the raindrop.
  4. Done ... The colour of the nodes now represent the values of your variable.


Making Selections

Alongside using the representations of your variables in the sidebar to filter your data, you can directly select data in the Graph, select a point and its neighbors or search for specific data.

Use the visual representation of your data to find patterns then zoom in to examine them in greater detail. Selecting a group of data points from the Graph allows you to conduct your analysis in greater detail.

Direct Selection

Selecting nodes directly in the Graph means that you can react quickly when you spot new patterns. Use the direct selection tool to click and drag your mouse over nodes. You can save these selections for later or keep them as insights.

Click outside of the direct selection to remove it and return to the whole dataset.

How to Make a Direct Selection?

  1. Start from your project's Graph.
  2. Zoom in to locate the nodes you want to select.
  3. Select the direct selection icon in the top left of the Graph - the icon with an arrow and a square with a dotted border.
  4. Click and drag your mouse over the nodes you want to select.
  5. Done ... You can then save it or inspect the sidebar graphs to see what characteristics it has.

Selecting Neighbors

Find important nodes in your Graph then identify linked data points sharing their significant features. For instance, selecting the neighbors of a node can help you find customers sharing characteristics with a key customer you are analysing.

A node has neighbours because Graphext calculates links between data points based on their similarities.

How to Select a Node's Neighbours?

  1. Start from your project's Graph.
  2. Locate the node you want to focus on - use filtering or the search tool if your Graph is large
  3. Use either the zoom icons in the top left of the Graph or the mouse to zoom in on the node.
  4. Click on the node.
  5. Click 'Select Neighbors'.
  6. Done ... Zoom out and inspect your new neighbours!

Searching for Data

Searching for data in the Graph means that you can quickly find specific nodes or groups that share similar features. The search tool matches your query with the tags that you gave your data when setting up your project.

Tags are the text that appears over groups of nodes. You can change what variable a tag represents in your project settings.

How to Search for Data?

  1. Start from your project's Graph
  2. Select the search icon at the top of the Graph window
  3. Start typing your search query
  4. As you type your data will be filtered to items that match your query
  5. Done ... You can then save it or inspect the sidebar graphs to see what characteristics it has.


Saving and Deleting

You can perform a number of actions on your Graph or Graph selections. These include deleting selections, clustering selections, saving selections as well as downloading a screenshot or capturing your Graph or as an insight.

Download a Screenshot

You can download a screenshot of your full Graph or after having made a selection. Screenshots will download as 'png' image files, which you can then edit yourself, send on to your teammates or include in a report.

The screenshot tool will take a snapshot of how the Graph currently appears in your project.

How to Download a Graph Screenshot?

  1. Start from your project's Graph.
  2. Apply any filters to your data - these will be replicated in your screenshot.
  3. Select the icon at the top of the Graph window representing a download - the downwards arrow pointing into a tray.
  4. Enter a title for your screenshot.
  5. Specify a width in pixels for the screenshot - height will be automatically calculated.
  6. Choose a light or dark theme - this affects the color of the text in your screenshot.
  7. Toggle the transparency of your screenshot - transparent images will not have a background color.
  8. Select 'Download'.
  9. Save the file to your computer.
  10. Done ... Share the magic with your team!

Capturing an Insight

Capturing an Insight from the Graph will save the current visual representation of your data to an insight card. You can use insights to share your analysis with others by presenting directly inside of the Insights panel or by exporting insights either individually or collectively.

Pressing the play icon at the bottom of an insight allows you to jump straight back into the point of your analysis at which you saved that insight.

How to Capture a Graph Insight?

  1. Start from your project's Graph panel.
  2. Make sure your Graph is displaying the representation of your data you want to capture.
  3. Select the 'Capture Insight' icon from the top of the Graph window - the line graph with a sparkling tip.
  4. Enter a title for your insight in the 'Capturing Insight' window that appears.
  5. Click 'Save Insight'.
  6. Done ... Navigate to your project's Insights panel to start editing your new Insight.
