Need help step-by-step how to code python for data visualization

1-  collect data using an API for TMDb

2- construct a graph representation of this data that will show which actors have acted together in various movies

3- complete all tasks according to the instructions found in the file 'submissions_og2.py' to complete the Graph class, the TMDbAPIUtils class, and the two global functions. The Graph class will serve as a re-usable way to represent and write out your collected graph data. The TMDbAPIUtils class will be used to work with the TMDB API for data retrieval.

4- Create a TMDb account to obtain an authentication token. 

5- Producing correct nodes.csv and edges.csv

ps. other files are examples found in the intenret (not sure if can help)
