PrismBarChart class

A token-styled vertical bar chart.

Bars scale against the largest value, labels sit underneath, and the tallest bar picks up the highlight colour by default. Screen readers get the data as a sentence.

PrismBarChart(
  bars: [
    PrismBar(label: 'Mon', value: 12),
    PrismBar(label: 'Tue', value: 19, color: Colors.teal),
  ],
)
