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.
This week uses US Flight Route. You can find it here on Data.World
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!
