On the site’s Instagram, there’s a series of posts that each list with icons, the chart types recommended based on what you can communicate or analyse with them. In total, there were 15 posts created, each with a particular category and color theme.
Essentially, these posts were an updated, Instagram version of the ‘What do you want to show’ page found here on the site, but with some new types of charts covered. The Instagram post didn’t provide a comprehensive list of charts and categories, but they were a decent introductory guide for selecting a chart for your needs.
However, the issue with Instagram posts is that everything is segmented into parts. Because of this, I thought it would be a good idea to organise all the icons and their categories into a single page.
Distribution
Charts that display frequency in the data and/or how spread out over an interval the data values are. Often, these chart types are useful for generating shapes or patterns that provide insight into the kind of distribution present in the dataset.

Overall, these are broad categories with many charts having some overlap between these listed categories. Also, some chart types missing from this list were designed with very specific usage.
You can find more information on some of these chart types on the homepage.
It’s a great collection. Thank you.
Sankey diagram is a very useful visualization to show the flow of data. Can you shed light which tools are best and easy to use to draw Sankey Diagram.
You can find a list of tools here and here.
