I have a question about CiviVisualize. So, I cloned the CiviVisualize repo from github in my C:\wamp64\www\drupal\custom_ext\CiviCRM Extensions Directory and then reran drupal. CiviVisualize comes up but the demo visuals are no where to be found. I'd love some help]1
This is likely a problem in how you have incorrectly set up the extension url in civicrm.
what is the right url to put there depends on where you have put the extensions folder, but on the good news, you will need to adjust your setting ones and it will work for every extension
