Improve clarity of "Relative Age Distribution" section

Multiple users have shared feedback that the "Relative Age Distribution" section under People is confusing. The app currently displays only five labels for ages with huge gaps. For example, one user asked if we were missing the 31-54 age bracket. There is also an issue with alignment where the label covers multiple bars.

Here's the labeling from the U.S. Census Bureau data for each bar in the app:

Obviously this example is not a solution, but it's clear that this section could use some design improvements so users are not confused.
