You can export your word cloud and word tree reports by navigating to explore>word tree.
Once you have used the "Show me Filters" to narrow your searches and the cloud and tree look the way that you want, you are ready to create the report. To do so, click "Publish Report" and select either "Word Cloud" or "Word Tree."
When you do this a pop up will appear with the image of the tree or cloud. There are different ways to save both of these.
Saving your Word Cloud:
When the Word Cloud pops up you will need to right click on the image and select "Save picture as..."
Saving your Word Tree:
When your Word Tree pops up. Click "Save as PNG."
