I've created a table of min and max lat/long coordinates for groups of locations. I'd like to use those to draw rectangular bounding boxes on a map and include other attributes as tooltips, not sure where to start. Some example groups below.
group entities minlat minlong maxlat maxlong
a 44 33.29 (122.45) 41.32 (111.75)
b 39 42.53 (110.97) 48.51 (94.90)
c 37 42.46 (100.34) 45.79 (94.83)
d 31 32.78 (83.97) 35.73 (77.86)
e 30 40.41 (96.41) 43.07 (89.40)
f 28 39.81 (80.47) 42.13 (76.78)
What's your data source? The current version of Tableau supports geography and geometry data types, and you could use that to build the polygons. In SQL Server, I would probably add a calculated field that takes the min/max coordinate ints and creates a polygon based on those with the geography data type. Regardless, you'll need coordinates for each vertex.
Take a look at this video. It shows how to overlay custom polygons onto maps. You need coordinates for each point, then you set marks to Polygon with the points on path.
I took your data and did a quick map. The yellow box looks like a strange shape, I might have mistyped a coordinate. It shows the example regardless though.
