Hi Seth

Welcome to the Lucidchart Community! Thanks for posting here! You can create Heat maps in Lucidchart by using templates. To access templates you can do so from the Documents Page or from within the document. For more steps on how to do this please have a look at the Work with Templates Help center article. From the Templates Gallery you can search "Heat maps" and that should give you some different template options. 

If you would like to import data from other sources the Link Google Sheet Excel or CSV Data to Lucidchart Diagrams article will be helpful to you. You can upload a data set visualize and manipulate it with any shapes as well as refresh and overlay new data. However do note that data linking is a feature exclusive to enterprise subscriptions. 

If you have any further questions please let me know! I hope this helps.
