How many chart types does Tableau support?
Tableau can support an infinite number of chart types. The possibilities are only limited by your imagination. Here’s why: Tableau is built on a database visualization language called VizQL. What is VizQL? It’s like SQL. The development of SQL led to a revolution in database technology. Suddenly, complex queries were easily described as readable text. What SQL did for data interactions in text form, VizQL does for data interactions in visual form. Sophisticated visualizations are described by declarative VizQL statements. The standard approach when developing analysis systems is to provide a set of pre-canned objects – bar chart objects, scatter-plot objects, etc. This legacy approach is similar to selling a database with six “pre-approved” queries rather than with a complete query language like SQL. Because all drag & drop actions in Tableau are based on VizQL, there is no limit to the number of chart types you can generate.
