Population Graph Series

A small experiment rendering population change over time for European countries as a 3d series. CSV data is loaded and prepared using danfa.js and then rendered as objects using the React Three Fiber wrapper around THREEjs. Prototyping of the individual scene components was done in Storybook.

Storybook view

The result is not immensely practical, but was interesting as an exploration of how data can be displayed on three axes.

Future Features

  • Add test coverage. Testing of the scene graph should be easier with the help of @react-three/test-renderer.
  • Use bezierTo rather than lineTo for a smoother visual change over time?
  • Explore if colour could enhance meaning, eg. could population density be a spectrum over the y axis?
  • One of the biggest problems is that it is hard to read the data. Consider adding interaction states that allow 1). visually highlighting a country and 2). overlaying a projection of marker lines in the graph's bounding box.
