If you have two maps, you can select to show neither, one of them or both. If you show both, you'll be able to name each map however suits your context, as you can see below.
To add your
Graph Commons map to your sumApp interface, first you need to get the 'Embed code' from your Graph Commons project.
First click on the 'Share' icon:
Then get 'Embed Code'
Copy the entire code string from the code field - take care to get it all!
In sumApp, go to 'Setup' and then 'Define Settings', and scroll down to the map settings area below the welcome text area
You can show/not show either map tab. You can give them distinctive labels.
Insert the 'embed code' you've copied from
Graph Commons into the map embed link field you want to contain your Graph Commons map - it doesn't matter to sumApp which you use.
Now DELETE all the code wrapped around the actual URL - everything on either side of, and including the " marks. What remains should begin with https: and end with embed.
It will look like this:
Don't forget to save!
Now go appreciate your dual-map interface
That's it!
