Semi-Circle Pie Chart
The main advantage of the Semi-Circle Pie Chart (also known as Semi-circle donut chart, Half pie chart) is that it takes two times less space than the regular Pie or Donut Chart for the same amount of data displayed.
Flexible pie chart
Pie chart is not limited to a full circle. You can set any angle for it to start on and any angle to end on. The chart will take care of the rest.
The chart’s properties startAngle and endAngle are responsible for it.

The prompt below can be used to build this chart with AI. For best coding results, use the most advanced AI models, like Claude Opus 4.6 and GPT-5.3-Codex. For more info and tips, check out amCharts AI docs.
Create a semi-circle donut chart occupying only the upper half of the visualization area, displaying seven categories ('One' through 'Seven', values 10 down to 1). The chart should have an inner hole to create the donut effect, with rounded corners on slices. Include three interactive sliders that control: start angle, end angle, and corner roundness in real time. Labels should be freely positioned. Animate slices on load with a smooth entrance. The chart should be 100% width at 500px height. Use amCharts 5 library.
