A radar chart rendered in a vintage hand-drawn illustration style — wind speed and air temperature across six times of day in a fictional English valley, complete with a windmill, kite, rolling hills, and ink-sketch clouds. Built with JavaScript on top of @kepano's Pele library, the result looks like a page torn from a 19th-century naturalist's almanac. The typography is all serif and italic, the color palette is parchment and watercolor blue-gold, and every data point gets a poetic caption instead of a number.

Radar chart wrapped in a full illustrated scene — windmill, village, kite, mountains — making the data feel like a story

Typography and annotation style mimic hand-lettered Victorian infographics, not a single pixel of generic chart chrome
