The view manipulation I decided to implement was selection and highlighting.

The updated plot provides a region where details are provided when a data item is selected. Making a detailed view felt like an appropriate and natural choice for this graphic. As I was working on it originally I found myself wanting to have the ability to obtain more information about points of interest. Before it was not possible to do this, but now it is.

• The kinds of elements that are selection targets in this graphic are the scatterplot data items (the circles).

• There are 2 selection types in this view.

  • Hover is used to imply that a mark can be explicitly selected to view more details about the mark.
  • Clicking, explicitly selects a mark and reveals more information about the data point in the lower right hand side of the plot.

• It has been decided that only 1 element at a time can be explicitly selected.

  • This is because the detail region was designed to display the details of only one player at a time.

• Explicit selection is shown via 4 mechanisms.

  • The selected mark increases in size to draw your attention to it.
  • The selected mark is colored black. This color was chosen because it nicely contrasts white, which is very dominant in this graphic and also appeared to stand out from the colors being used categorically.
  • This one's more subtle, but the selected mark is bubbled to the top layer of the graphic. Some points are clustered together, and if the selected mark's Z dimension didn't change the marks surrounding it would clutter the previous two changes being done to show that the target is being selected.
  • The final mechanism that shows that a mark has been selected is the most obvious. The detail region will be repopulated, with the information associated to the player being selected.
