Release 3.2.1 D3.V5 Fix

[msusol]

• Fix missing labels and other D3.V3 to D3.V5 issues.
• Revert the indexing changes i.e. (startIndex - 1).
• Removed some unused GLOBALs.

@bmabey Are you available to merge this PULL request with the D3.V5 fix?

[bmabey]

Were the startIndex changes causing the problem? I thought they had properly defaulted it so it would not have changed anything.

Regardless, thank you for doing this and making such a complete PR and release! I've merged it in and released it.

I don't understand why the start Index change was made. I reverted all of those changes, and didn't see the need for the change. It wasn't what caused the main issue though.

There was a line of javascript chart.attr("class", "xaxis").call(xAxis); in ldavis.v3.0.0.js not related to D3.V5 upgrade that stopped working i guess. It has been there for awhile. I compared to original D3.V3 version.

There was also a missing D3.V5 function change (sqr root).

You're welcome!

@msusol No, those changes are necessary for custom start_index to function.

I have created a new issue (#265) for this.

@msusol
#266 should revert only the changes that involves startIndex.
