[D3: Tree Map]: Does not display in Safari about testable-projects-fcc

[Christian-Paul]

@no-stack-dub-sack I just tested it on edge and IE. the visualization doesn't show up on either. The modals show up on both, but the styles are messed up on IE.

The reason the chart doesn't appear is because of how the data selection works. We set the chart to check the url to decide which dataset to display, but it looks like IE/Edge doesn't support this method.

new URLSearchParams(window.location.search);

This is the code responsible for the error: 'URLSearchParams' is undefined

According to Mozilla, this isn't supported on IE or Safari (and I'm getting the same error on edge)

@no-stack-dub-sack I have updated my codepen to make the TreeMap appear on Safari, IE, Edge, Firefox, and Chrome.

@no-stack-dub-sack I submitted PR #72 a week ago. Do you have any questions about it?

Everything works for me on FF, Chrome, Canary and Safari, testable project here : https://lakston.github.io/d3-heatmap/

So I guess we can close this ?

Closing because this is outdated. We will address cross-browser support in an upcoming phase.
