The Pinterest API data collection possibilities are limited to the user's own pins and relationships. However, we can extract more data through web scraping techniques, but usually such an approach has its own limitations due to scalability, maintenance, and complexity issues.

For the purposes of this chapter, we will demonstrate how to analyze scrapped data in graph structures and identify groups of related topics.
