Manual SVG Donut Chart

Building Segments with Stacked stroke-dasharray Circles

Each data segment in a manual donut chart is represented by its own circle element sharing the same center and radius, with stroke-dasharray set to show only that segment's proportional arc length and stroke-dashoffset rotated to position each segment consecutively around the ring, building up the full donut chart from multiple overlaid circles.

• Each data segment gets its own circle sharing the same center and radius
• stroke-dasharray length is proportional to that segment's data value
• stroke-dashoffset positions each segment consecutively around the full ring

When a Manual Approach Makes Sense Versus a Library

Building a donut chart manually in raw SVG works well for a simple, lightweight dashboard widget with only a few data segments and no need for complex interactivity like tooltips or legends, while a dedicated charting library remains the better choice for more complex dashboards needing many chart types, animations, and built-in accessibility features.

• Manual SVG suits simple, lightweight widgets with few data segments
• Charting libraries suit complex dashboards needing many chart types and features
• Manual approach avoids a library dependency for genuinely simple use cases
