Plotly.js is a charting library that comes with over 40 chart types, 3D charts, statistical graphs, and SVG maps.

Plotly.newPlot("myPlot", data, layout);To display a pie instead of bars, change x and y to labels and values, and change the type to "pie":
const data = [{
labels: xArray, values: yArray, type: "pie"
}];To display a donut instead of a pie, add a hole:
const data = [{
labels: xArray, values: yArray, hole: .4, type: "pie"
}];Source Code let exp = "Math.sin(x)";
// Generate values const xValues = [];
