Found a sample code for visualization of direction here:
https://habr.com/post/129344/

but the dataset is not available, and language is not English. Do you know any source Visualization of Directionto create similar graph? Thank you.

I think what you have here is a network graph. Or perhaps directed network graph, which you maybe meant to explain.
Try if NetworkX module can be of help. Or just search online for Python (directed) network graph.
