The Graphic Continuum is a poster created by Jon Schwabish and Severino Ribecca (the man behind the Data Visualisation Catalogue). It lists almost 90 different chart types and organizes them into five large groups: distribution, time, comparing categories, geospatial, part-to-whole, and relationships. Some of them are connected across groups where there are further similarities.
The poster is printed very nicely and makes for a great piece of wall art to stare at when thinking about data, and maybe to get an idea for what new visualization to try.
