Smoothed D3.js Radar Chart
This smoothed D3.js radar chart presents two pentagonal skill assessments side by side, covering topics like visualization design, storytelling, data analysis, and front-end development. Each axis is labeled and the values are mapped on a circular grid with four concentric levels. The chart is rendered in SVG and uses the Rough.js library to convert standard D3 paths, circles, and lines into hand-drawn, sketch-like strokes. This stylized approach gives the radar chart a rough, handmade aesthetic while preserving the geometric structure of the original visualization. Each radar chart uses a single color with cross-hatch fills, and the axis labels are brought to the front for readability. The visualization is built with D3.js version 3.5.6 and is available under the MIT license. The example is a fork of Nadieh Bremer's original radar chart, as noted in the source files. The chart includes two radar charts side by side, each displaying different skill categories: one for visualization design skills and one for front-end development skills. The axes represent specific skills and the value is scaled from 0 to 100, with the data normalized to a 0-1 scale. The chart is rendered using SVG and styled with a clean, open-sans font. The rough.js library is used to give the chart a hand-drawn, sketch-like appearance.

"description": "This radar chart compares two sets of five skills each, with each skill normalized to a scale of 0 to 100. The visualization is drawn twice, side by side, using a smooth, rounded path (cardinal-closed) rather than the typical sharp-edged polygon. Each chart is color-coded: one in yellow (#EDC951) and one in red (#CC333F). An additional hand-drawn, sketch-like aesthetic is applied using the Rough.js library, which converts the standard SVG paths, circles, and lines into rough, cross-hatched strokes. Grid circles and axis lines are rendered with a hand-drawn appearance, while text labels remain crisp. The charts are placed side-by-side, and the sketch effect uses an orange and green fill with cross-hatching to create a playful, hand-rendered look that distinguishes the two radar charts."
