Geo: Hard to read number of actual numbers

The new graphs look great, but it's hard to find out the real numbers:

It looks like the number of actual repository syncs is "4x", but I can only see the full numbers if I use "Inspect Element":

Is there a way we can get this information either via the tooltip or somewhere on the graph?

Design

• We should always have enough green, grey or red so we can see the text being shown.
• Showing the percentages instead of the actual number.
• The actual numbers show in a tooltip.
