It would be nice to include in the generated diagrams the (non-)nullability of some columns.

a suggestion on how this could look:

image

name is NOT NULL, while label is nullable

diagram 
@startuml
!define table(ename, dbname) entity "<b>dbname</b>"

!define pkey(x) {field} <b><color:DarkGoldenRod><&key></color> x</b>
!define fkey(x) {field} <color:#AAAAAA><&key></color> x
!define column(x) {field} <color:#EFEFEF><&media-record></color> x
!define rcolumn(x) {field} <color:#a19f9f><&media-record></color> x
