-## Lollipop Chart Features
-
-Lollipop charts offer several advantages:
-
-- Clean visualization of point data with connecting lines to a baseline
-- True side-by-side grouped display for easy comparison between categories
-- Each lollipop maintains its position from dot to baseline
-- Customizable appearance with parameters for dot size, line width, and colors
-- The `dodge_width` parameter controls spacing between grouped lollipops
-
-The side-by-side positioning for grouped lollipops makes them visually distinct from dumbbell plots, which typically connect related points on the same line.

-## Lollipop Chart Features
-
-Lollipop charts offer several advantages:
-
-- Clean visualization of point data with connecting lines to a baseline
-- True side-by-side grouped display for easy comparison between
-  categories
-- Each lollipop maintains its position from dot to baseline
-- Customizable appearance with parameters for dot size, line width, and
-  colors
-- The `dodge_width` parameter controls spacing between grouped lollipops
-
-The side-by-side positioning for grouped lollipops makes them visually
-distinct from dumbbell plots, which typically connect related points on
-the same line.
