wordcloud2 help required
I have downloaded wordcloud2.js to create my own word cloud (attached)
The included documentation is 'scant' to say the least
I have a page with the code:
All I keep getting is the following error:
Line: 754
Error: Unable to get property 'dispatchEvent' of undefined or null reference
which refers to the following:
It is highlighting the reference el.dispatchEvent(evt);
Has anyone had practical experience of using wordcloud or can fathom out it's implementation because I have been trying for hours with no joy.
Regards
