https://www.smartdraw.com/ - SmartDraw has done this for about 20+ years. I can draw entire flowcharts using keyboard shortcuts (although I still have to click a button for split paths) and everything is automatically spaced correctly / adaptively even if I delete shapes.
The other chart types I use this for are org charts, mind maps, and network diagrams which are all similarly automated.
