Describe the issue you are experiencing

No matter what name an entity has ("Sun", "Sun Long", or "Sun Long Long Long"), the last few letters are always truncated.

We're clearly scaling the chart to attempt to fit the name, but it's odd that we scale it just slightly not long enough to fit the last letter.

Describe the behavior you expected

Display entire name up to a point, but truncate if it becomes too long (maybe over 25% of the card width?)
