Increase lisibility

One is ERD from my tool, and other one from maxscale. could by nice if you can force arrow of child => parent, to force (parent table on the right and child on the left), it's will result a better view of the diagram from first side

I saw that my tools gived some ideas to you =), (like with color on table and link), i ask myself how it's work with many table child => one parent, unfortunaly i couldn't see more than 3, bug ?

I could share my script to got a better display from start, in exchange i will ask you library you used for it and the display of the box.

and increase placement with JS can be nice to make it more condensed in second part.
