At Heart's a Stereo

A data visualization

Data Set

Dependent Vars.

Variable 1 (Bar Height)

To select variables to visualize, use the dropdowns on the right side. To play, reset, and adjust the time speed, use the buttons in the lower left. You can also advance or rewind the time one step at a time by clicking on the times on the bottom right bar. Two variables is more fun! Try hovering over bars to see exact data values.

This is a data visualization that I wrote from scratch over the course of a few days. The visualization is written in JavaScript using HTML5 Canvas. The concept for this visualization was created by Chia-Yi Hou.
