tmp permissions g_strat.export_gate_hierarchy_image() on windows 11

[rwbaer]

This is a feature request related to a problem. Please describe.
Windows 11. Trying follow tutorial 3 and use the graphviz code to create a figure. Pretty sure graphviz is installed but the directory g_strat.export_gate_hierarchy_image() tries to write to seems to not have permissions.

# Return a gating hierarchy image from the gating strategy object
nrerated\n")
g_strat.export_gate_hierarchy_image('D/VSCode_Projects/UsingFlowkit/gs.png')
Image('D://VSCode_Projects/UsingFlowkit/gs.png')
g_strat.export_gate_hierarchy_image() 

On my windows machine it tries to write to a tmp directory that apparently doesn't have rights. Not sure why it doesn't have rights, but It would be nice if I could specify where this write was to take place to. Then, I could probably work around the issue. Here is the output:

Error: dot: can't open C:\Users\rbaer\AppData\Local\Temp\tmpt23j7q9x: Permission denied
