javascript - Removing Tooltip from Google Charts WordTree -

i'm trying remove tooltip google wordtree chart.

on corecharts, there can either set enableinteractivity: false or set tooltip trigger none:

tooltip:   trigger: 'none' 

however, doesn't work wordtrees, , configuration options not mentioned in documentation. furthermore, there no onmouseover other charts use suppress further actions.

can think of way can hack solution? here jsfiddle example wordtree: https://jsfiddle.net/b70wrfoc/

update: i'm fine suppressing javascript hover events on parent div if makes easy.

much appreciated!

alright, it's not pretty, job. workaround put overlay 0% opacity on top of chart

html

<div id="wordtree_container" style="width: 800px; height: 400px;">   <div id="wordtree_explicit" style="width: 800px; height: 400px;"></div>   <div id="wordtree_overlay"></div> </div> 

css

 #wordtree_overlay{     position:absolute;     top:0;     bottom:0;     left:0;     right:0;     background-color:black;   }
