I reduced the number of records (than in twitter demo) due to the limit size of upload file.
(Mac Only: FMwithD3.fmp12)
I remade this to achieve cross-platform. (FMwithD3v5.fmp12)
Some caveat:
Now it works on Win and Mac.
But I had to downgrade D3 version from 6 to 5 for Windows.
d3.rollup/d3.group are not available in v5.
Previous(v5) way is less intuitive. And also in IE11 Arrow Function is not supported. It makes readability worse.
