I logged d3.json function after invoked with url argument and saw a promise so I figured it was “thenable”
They must’ve changed it since verison 4. I tried to look through the docs for about 10 seconds to find the actual documentation to see what else they might’ve added but I remembered d3’s docs gave me nightmares, so I’ll leave the rest to you.
Yes. I stated why I think it’s not working. That FCC example is using version 4.2.2. I’m assuming you are using 5 or greater and that’s why the json call wasn’t working in that fashion.
