I recently installed MySQL Workbench 8.0.12 and MariaDB 10.3.9. I created my database and want to start fine tuning indexes and views. I can run a query with the EXPLAIN button and get the results in the tabular format (Tabular Explain). When I try to select "Visual Explain" from the dropdown menu, it switches back immediately to Tabular Explain. I tried almost everything and cannot switch to Visual Explain. Any ideas? Thanks!
