Use a chart-level empty state for charts without valid data
Currently when a chart does not have valid data, it renders totally blank but the tooltip can still appear.
We should have an empty state of some kind, to indicate "No data found" or similar, and then probably turn off the tooltip?
Design
When there is no data to display, we should:
- Disable the popover
- Hide the x and y axis labels
- Hide the zoom/scroll bar
- Keep the chart title
- Replace the chart svg with an empty state illustration and a 'no data to display' message:
