Quand utiliser un Lollipop Chart
You have many categories
Thin stems leave room to read twenty or thirty rows that would feel heavy as bars.
The values are all large
Dots at the end of a stem show small gaps between big numbers better than a block of ink.
You want a second measure
Size each dot by another column, such as a sample size or a population.
You want a lighter look
A lollipop chart reads as less dense than a bar chart and sits well in a report or on a page.
