Currently working on visualization for DKAN using Chartjs. Module is in very early stage, but basically working as far as I can tell: https://www.drupal.org/project/dkan_chart

You will just need to enable the module and after that you will find a "tab" called "Visualization" on each dataset node that has a distribution in the datastore. Then you can try out some visualizations. If using the react frontend you may need to edit a dataset to see the "Visualization" tab.

Not really meant for production at this moment, but wanted to let folks know. I will still improve on this.

Happy if someone likes to test and maybe leave a feedback.
