build(deps): bump apexcharts from 6.6.1 to 6.7.0 in /ui/changes

[dependabot]

Bumps apexcharts from 6.6.1 to 6.7.0.

Release notes

Sourced from apexcharts's releases.

💎 Version 6.7.0

The headline is a new chart type, sunburst: a hierarchical radial chart (a nested pie and donut) that draws tree-structured data as concentric rings, one ring per level of the hierarchy, with each child arc nested inside its parent's angular span. This release also brings rounded corners and inter-slice spacing to pie and donut slices, a parliament (hemicycle) layout for the unit chart, an optional hover tooltip on point annotations, and a broad reliability and security pass. Two behavior changes are worth reading before you upgrade: a legend click on pie, donut, and polarArea now toggles the slice in and out, and the premium features now require an entitled plan rather than just any valid key. Every existing config renders unchanged.

✨ New

The sunburst chart type

chart.type: 'sunburst' renders a hierarchy as a ring of nested arcs: the first level fills a donut around the centre hole, and each deeper level stacks outward, with every child arc constrained to the angle of its parent. It is a non-axis chart (dispatched like pie or treemap) and is tree-shakeable via import 'apexcharts/sunburst', so it adds nothing to the core bundle unless you use it. It is a free chart type, not gated.

Data is the familiar x / y shape with a children array for nesting:

new ApexCharts(el, {
  chart: { type: 'sunburst' },
  series: [{
    data: [
      { x: 'Mobile', y: 55, children: [
        { x: 'iOS', y: 30, children: [
          { x: 'iOS 17', y: 18 },
          { x: 'iOS 16', y: 9 },
        ]},
        { x: 'Android', y: 23 },
      ]},
      { x: 'Desktop', y: 33, children: [
        { x: 'Windows', y: 20 },
        { x: 'macOS', y: 10 },
      ]},
    ],
  }],
  plotOptions: {
    sunburst: { innerSize: '25%', borderRadius: 5, spacing: 1 },
  },
})

plotOptions.sunburst.innerSize sets the centre hole (percentage or pixels), borderRadius rounds the arc corners, and spacing opens a gap between neighbouring arcs. Colours, stroke, legend, and title behave as they do on pie and donut.

Rounded corners and spacing for pie and donut

plotOptions.pie.borderRadius rounds the corners of each slice, and plotOptions.pie.spacing opens a gap between slices, so a pie or donut can read as a set of separated, soft-cornered segments rather than a solid wheel. Both apply to polarArea as well.

A parliament layout for the unit chart

The unit chart (introduced in 6.6.0) gains a plotOptions.unit.arc layout: a parliament or hemicycle that arranges the marks as seats in concentric arced rows across an annulus, filled in category order. It is the natural shape for seat counts and any part-to-whole where a semicircle reads better than a grid. The gather animation is now tunable too, with configurable easing and enter motion.

Optional tooltips on point annotations

Point annotations can now show a hover tooltip, so an annotated marker can carry its own explanatory text without a separate custom element.
