Data-Ink Ratio Sculptor (2D)

Interactive 2D infographic-design lab: toggle drop shadows, fake-3D bevel shading, redundant data labels, heavy borders and a decorative background on a canvas bar chart and watch Tufte's data-ink ratio recalculate live from an actual pixel count of every render.

Edward Tufte argued that a well-designed chart should maximize the fraction of its ink that actually encodes data. This simulator renders a real 2D canvas bar chart and lets you add or remove five classic pieces of "chartjunk" — drop shadows, fake 3D bevel shading, redundant data labels, heavy borders, gridlines and a decorative background — while a live readout recomputes the data-ink ratio from an actual pixel count of two offscreen renders. Watch how quickly decoration can outweigh the data it's supposed to support.

⚙ Under the hood

Toggle drop shadows, 3D bevels, gradient panels, gridlines and border frames on a 3D bar chart and watch Tufte's data-ink ratio recalculate live from the real footprint area of every rendered object.
