Concentric rings mark the 0.25 / 0.5 / 0.75 / 1.0 steps of each axis. Each axis has a label at its tip and an optional caption (the benchmark / metric name). Each series is a closed polygon with small dots at axis intersections; one series can be accented and rendered on top with a thicker stroke.
When to use
- Model capability profile across 6-10 evaluations.
- Product feature matrix where all axes share a 0-100 "coverage" scale.
- Before / after release comparison.
Input shape
{
"data": {
"axes": [
{ "key": "reasoning", "label": "reasoning", "caption": "GPQA Diamond", "max": 100 },
{ "key": "coding", "label": "coding", "caption": "SWE-bench", "max": 100 },
{ "key": "terminal", "label": "terminal", "caption": "T-Bench 2.0", "max": 100 }
],
"series": [
{ "label": "previous release", "caption": "four months ago", "values": { "reasoning": 86, "coding": 62, "terminal": 58 } },
{ "label": "current release", "caption": "accent", "accent": true, "values": { "reasoning": 94, "coding": 75, "terminal": 82 } }
]
}
}
Visual rules
- Axes always start at 12 o'clock and go clockwise.
- Accent series always drawn last so its polygon sits on top.
- At most 4 series before legibility suffers.
