Be aware that the animation is processor intensive: close browser window (tab) after use.
The animation shows 4 aspects of the development of a project:
- X-axis: Age of a project (oldest Wikipedia’s are 8+ years)
- Y-axis: Number of articles per project
- Circle size: Number of editors per project
- Color: Maturity of content (blue=mostly stubs, violet=mostly articles with over 0.5 Kb text)
Click on any circle during or after the animation to show the full history of one Wikipedia. In this example you see clearly see how the Spanish Wikipedia restarted its community after the so called Spanish Fork.
You can switch between linear and logarithmic scale (last one works best), show all languages at same size, show/hide language codes. You can switch between Wikimedia projects, and change the size of the animation, see links below the chart.
