I want to build a dynamic representation of the most popular events in a region over a certain period of time. I was thinking Europe, but if there is no dataset available I could do it for the US. Regarding the time I would like to have at least 2-3 years, even though 10 would be better.
What I need is the date, event name, geolocation and number of attendees (or estimate number of attendees). It would be even better if events are already categorised by type (sport, protest, etc..).
