Hello, Madonis

The ability to change the graph path at any time seems very useful.

However, I modified it to SelectBox because I thought it would be more useful to know what the current graph path is, rather than the drop-down menu.

Please share your opinion.

@shinhanbyeol I think that's a great idea, Select will work better
