## Connection Graph Explorer - Help

×

A tool for visualizing and understanding how variables are connected and promoted within your OpenMDAO model by examining their connection graphs.

1. Click on any system (⚙️) to see all connection graphs involving that system
2. Click on any variable (i or o) to see only the connection graph for that variable
3. Use the zoom controls in the top-right corner:
   - + to zoom in
   - − to zoom out
   - ⊙ to reset to 100% zoom
   - ⊡ to fit entire graph to window
4. Click and drag on empty space in the graph window to pan/move the graph around
5. Keyboard shortcuts: `+` zoom in, `-` zoom out, `0` reset, `F` fit to window
