In 1990 I used AutoLISP to setup a tool that the state legislature would use for redistricting after the census. The AutoLISP let them interactively assign counties to districts while seeing the voter numbers and then export it to a CSV file which was read into a database. They could also export from that database back into AutoCAD using AutoLISP.
Redistricting with AutoLISP - that's a use case I never imagined. Interactive county assignment with live voter counts, bidirectional CSV sync. Democracy infrastructure in a CAD macro.
