Outlined Map Visual

[nicholasanford]

Hello,

We are trying to make a heat map that shows two data sets at the same time: how many sales are in a state and which states a company is filing tax returns in. The heat map was easy enough, but we haven't been able to find a custom map that outlines states. We've found some that filled states or showed saturation, but nothing that only outlines the state. We made the below graphic by manually drawing out the states.

Does anyone have a custom map or know how to create one for what we're looking for?

Thank you,
Nick
