How 4db444/used_car_price_predictor works
This is a Python used-car data analysis and feature-preparation toolkit, not a complete prediction application: the tree has no implemented app or model code, and the README is empty. Its available workflow covers loading data, cleaning it, engineering and encoding features, analysis, and visualizations. The source exports these operations but shows no central pipeline connecting them, so the graph includes only evidenced calls and writes; loader and saver implementations were not sampled.
