Lollipop charts are a great data visualization technique. Data visualization professionals and business analysts like them for a good reason. They can be used in similar situations as bar charts and column charts, but they have the advantage of producing a cleaner-looking picture.
The sticks of the lollipops are thinner than the bars/columns, which allows the chart to "breathe", while the lollipops force the reader to focus on the most important part of the chart - the values.
Jon Peltier, Stephanie Evergreen and Jon Schwabish all wrote their own guides on how to produce lollipop charts in Microsoft Excel - "the primary data visualization tool for most of the world", according to Schwabish. These kinds of guides are necessary because lollipop charts are not included in the default set of charts found in Excel.
All of these guides work well for producing lollipop charts in Excel, but they all have one flaw: they take time to complete.
Ideally, you wouldn't need a guide to produce a lollipop chart in Excel...
