You can now make a copy of a published visualization on your site. The copy of the visualization will carry over the configuration option of the visualization but not the detailed metadata. The copy will be created as a private draft where you can finish configuring your new visualization.
Please note that the copy feature is not available on maps created with the new visualization tool.
How to Make a Copy
To make a copy first navigate to the published version of the visualization you are copying.
From there select the three ellipses from the Action Bar and choose Copy this asset.
This will bring up a modal where you can choose the name of your new visualization, once you have done so click Copy.
After selecting Copy, you will be taken to the draft of your new visualization!
