many such offerings around, it seems. What I am looking for however, is a tool which I can use / script against. My use case is to produce (relatively straightforward) db diagrams from some model descriptions I have (part of another process). I have table names, column names, and relationships in a memory structure, and want to draw an ER like diagram. Currently looking at producing this wit plantuml, generating the puml file form my data, then running plantuml to generate the png / svg. Looking around i find most tools in this corner are either full fledged DB design tools with their own editor, but no API. The others like this and things like dbdiagram.io usually are focused online only, which is not an option for me. Any suggestions greatly appreciated...
