This week I hone in on majority of those spatial calculations within Tableau. I love the flexibility that Mark Layers allows us to have. Prior to Tableau 2020.4 maps could only have 2 layers and creating this hub and spoke style map would require some serious data preparation. This workout requires 6 calculations.
- Dashboard Size: 800 x 700px
- 1 sheet
- Create a map with FOUR layers: Airport Origin (Black circle), Airport Destination (Blue Square), Line between them and a dynamic buffer area
- Buffer should be in miles and adjustable
- Should only include destination airports that are within the buffer distance.
When you publish your solution on Tableau Public make sure to take the time and include a link to the original inspiration. Also include the hashtag #WOW2022 in your description to make it searchable!
