Pure CSS Spider / Radar Charts Are Here in st-core.fscss v2
No SVG. No canvas. No JS charting library. st-core.fscss v2 now draws spider (radar) charts the same way it draws area and line charts: FSCSS arrays, CSS custom properties, and clip-path: polygon() . The result looks like a modern product dashboard — skills matrices, multi-axis scores, team comparisons — and the payload stays tiny. The module Source: github.com/fscss-ttr/st-core.fscss Why this…
st-core.fscss v2 now draws spider (radar) charts using only CSS arrays, custom properties, and the clip-path: polygon() function. This approach results in a lightweight, modern look without the need for SVG, canvas, or a JavaScript charting library. The charts feature token-driven colors, soft polar geometry, and composable layers that stack as plain divs.
Multi-series charts are created by adding more layers with their own accent colors. The charts utilize native CSS inheritance, making it easy to create multiple team cards or dashboards without the need for a state tree. The total CSS for a chart class is only a few kilobytes, making it much lighter than other charting libraries.
