This experimental exploratory data visualization invites the user to compare categories of interest along indicators like popularity, activity of members or social closeness. How did the use of the platform grow in the past decade. How was it used by the audience? A responsive storytelling module enriches the visualization with valuable context and creates a playful story driven experience. The collected data was scraped from the platform and contains more than 75.000 meetup events of ~3.000 groups of the past 10 years which were located in Berlin.
