• ChartBar - chore(chart bar): convert to typescript #11727
• ChartBoxPlot - chore(chart box plot) - convert to typescript #11728
• ChartBullet - chore(chart bullet): convert to typescript #11756 | chore(chart bullet): convert to typescript part two #11758
• ChartDonut
• ChartDonutUtilization
• ChartLegend
• ChartLine
• ChartPie
• ChartScatter
• ChartStack
• ChartTheme
• ChartThreshold
• ChartTooltip
• Patterns
• ResizeObserver
• SparkLine

I have not included Skeletons since it is in beta.

@thatblindgeye each component has multiple examples.

• Should I create a single PR for each component updating all examples or one example per PR?
• The file structure should be similar to react-core i.e. each example having its own .tsx file ?

I'd say create 1 PR for each set of component examples. So 1 PR for ChartArea examples, etc. In the PR just make sure to link it to this issue with the "Towards" keyword rather than "Closes"
