{"version":"1.0","type":"rich","title":"Internet Users by World Region","description":"This visualization presents multiple line series that track the number of Internet users per 100 people across seven world regions, from 1990 to 2015. The chart highlights that North America was already saturated early on, while the East Asia & Pacific region shows dramatic growth. Built with D3 v4 and the MetricsGraphics library, it loads CSV data from VizHub, parses years as dates, and nests entries by region using `d3.nest`. The chart renders responsively to the window’s dimensions, with a category-10 color scheme, a shared legend, and custom tick formatting that converts billions into \"B\" suffixes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/056c79bd1b064c4bba053157f0434249?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
