Before we close this chapter, I wanted to share a quick tip that I saw on LinkedIn some weeks ago. The post describing the following exercise came from Klaus Schulte, a German professor and 2018 Iron Viz Champion.

He shared that he had built a grid map by using custom geocoding. Let’s try to replicate it!

Download hex map data somewhere or create it yourself. For this exercise, you can use the hex map data from my Tableau Public or GitHub: https://github.com/PacktPublishing/Mastering-Tableau-2023-Fourth-Edition/blob/main/Chapter09/hexmap.xlsx.

  3. Double-click on State/Province:
