 ### Customize Displayed Text with a Text Template
 
 To show an arbitrary text in your chart you can use [texttemplate](https://plot.ly/python/reference/#pie-texttemplate), which is a template string used for rendering the information, and will override [textinfo](https://plot.ly/python/reference/#treemap-textinfo).
