Word Cloud visualization improvements

[arikfr]

Additional configuration options:

• Limit on words
• Ability to pass the word frequency

[dermatou]

Not quite sure how the word cloud is supposed to be working:
here, with 20 results, word cloud is not properly counting or showing the results: https://demo.redash.io/queries/4263
Same query, with 15 results, all fine: https://demo.redash.io/queries/4262

Is this a current limitation or would this be a bug?

Any plan to implement this feature?

[mohamagdy]

@arikfr one of the configuration options is implemented as part of #3668.

The bug @dermatou addressed most probably fixed also as part of #3668 by setting a max value for the size of the texts in the Word Cloud.

We face the same issues. Word count works with 75 lines (5 unique values).
When we have 100 lines (same 5 unique values) only a single random word is presented.

Was accepted as a Redash issue: #3730
RCA is frequent words that are too long, and don't get into the widget.
A workaround is limiting the length of words (in our case 7 chars).
