Radial Chart with Labels

Q: How are the names placed on the rings?

A radialText mark in its own decorative polar() layer, which starts where the rings start and reads degrees (0 to 360) and pixels (0 to 110). Each label sits in the middle of its ring, 38 + index * 16 pixels out, a little past the start, turned by minus its angle to lie along the ring, at fontSize: 11, filled white.

Q: What happens to the labels if I add a browser?

The labels are worked out per row: ringWidth divides the 30 to 110 pixel band by the number of rows, so a sixth browser gets its label on its ring. If you change the band, change the 30 and 110 in ringWidth and the radius scale's range together, and keep names short so they stay inside the bar.

Q: Are white labels readable on every color?

The labels are white on the ring's color. On light --chart-N colors the contrast drops, so pick darker chart colors or fill the text with var(--background). They're short names on purpose; the tooltip carries the value.

Q: How do I change where the rings start?

polar() takes startAngle and endAngle in radians, with zero at twelve o'clock and positive values clockwise; rechartsAngle converts Recharts' degrees. Here the rings start at six o'clock, rechartsAngle(-90), and sweep counterclockwise, as shadcn/ui's Recharts version does. Move the labels' layer's startAngle with the rings'.

Radial bars with each browser's name printed in white at the start of its ring, so the chart reads without a legend. Built in Vue.

About

Pick it over the plain radial chart when the card has no legend and the names should sit on the data. It suits a few short names: five browsers fit, longer labels run past the bar. For long category names, a horizontal bar chart with labels inside the bars reads better.

Five rings over muted tracks start near six o'clock and sweep counterclockwise, Chrome on the inside. Each browser's name is written small and white where its ring begins, tilted with the arc.

Usage

<script setup lang="ts">
import ChartRadialLabel from "@/components/charts/chart-radial-label.vue";
</script>

<template>
  <ChartRadialLabel />
</template>

Customize

The rings are two radialBarAngle marks on the browser band: the muted tracks at the largest value, which read the pointer, then the values in a decorative() layer, each in its browser's var(--color-<browser>).
The names are a radialText mark in a third, decorative polar() that starts where the rings do and turns once on an angle scale of 0 to 360, so a label's angle is degrees from the rings' start.
Each label's radius is 38 + index * 16 pixels, the middle of its ring. rotate is minus its angle, which lays it along the arc, and the text is the browser name with its first letter capitalized.
A label's angle is 5 degrees plus half its width at that radius (about 5 pixels a letter), so the name starts just past its ring's start, as Recharts' insideStart does.
The tooltip passes hideLabel, nameKey: "browser" and valueKey: "visitors" to ChartTooltipContent, so it shows the browser and its visitors.

Does it work in a small card?

The ring and label radii are fixed pixels, drawn for the 250-pixel square that max-h-[250px] caps. For a smaller card, scale the rings' range and the labels' radius scale and ringWidth together, or give the ranges functions of the layout's radius.
