+## Dataset
+We combined many datasets from Kaggle:
+- [athlete_events.csv](https://www.kaggle.com/datasets/heesoo37/120-years-of-olympic-history-athletes-and-results?select=athlete_events.csv)
+- [noc_regions.csv](https://www.kaggle.com/datasets/heesoo37/120-years-of-olympic-history-athletes-and-results?select=noc_regions.csv)
+- [gdp_per_capita.csv](https://data.worldbank.org/indicator/NY.GDP.PCAP.CD)
+- [pop_count.csv](https://www.kaggle.com/datasets/aliaamiri/historical-worldwide-countries-population)
+- [conflicts.csv](https://www.kaggle.com/datasets/nikolaosroufas/history-of-large-conflicts-between-1800-2024)
+
+We first [merged](milestones/milestone1/merge_datasets.ipynb) them into a single [olympic.csv](milestones/milestone3/olympics.csv) file. We then [created individual](milestones/milestone3/extract_viz_data.ipynb) extracted datasets per visualisation topic (see `website/data` folder) to make our website run smoother.
