Useability: The timeseries line graph and bar chart will allow different areas with the same name to be displayed together by adding as selected areas. However there is no disambiguation to show which is which e.g. Regions and Combined Authorities all have areas called West Midlands, East Midlands, North East. Whilst the names are the same the areas are different and the graph doesn't show which is which. I spotted this on the FDI datasets (only published at Region, Country, CA - but will be true of other datasets also.
