What I'd like to do is have Alteryx create a set of polygons (based on lat/long centroids) that fill in the entirety of a given geographic 'container' like a state or country, so that I can append this geometry data point to a data set being sent to Tableau.
Some more context:
- For a given geography (a state or a country), we have created clusters based on postal codes and sales metrics.
- Each of those clusters can range from a single postal code to hundreds.
- When I create polygons via the Poly Build tool (selecting Convex Hull), I get shapes like this (in the state of California):
But what I would like to do is flesh those shapes out so that they look more like this:
I know I can assign a dimension in Tableau as a geographic role (i.e. create from postal code), but the size of the data we're using results in that process (and all subsequent filtering etc) taking a loooong time. So if I could just have Alteryx generate the shape files and pass those in to Tableau, then they should (in theory) render much faster. But I am at a loss as to how to create those shapes.
Hi @DavidThorpe . Thank you for the suggestion (and sorry for the slow reply). I do see how that does fill in more of the 'white space' around the clusters, but I wasn't able to see how to make the revised shapes actually resemble polygons shapes that would, when combined, look like a traditional state/country. I'll play around some more but wanted to see if you see this on your end as well.
