This area chart displays quarterly worldwide user numbers for Twitter, Instagram, and Facebook from Q1 2016 through Q4 2020, with each dataset layered as a filled line using gradient colors. The chart uses Chart.js with the chartjs-plugin-zoom extension to enable interactive panning and zooming via mouse wheel or pinch gestures. It renders to a Canvas element within an 800x400 pixel container, and includes tooltips and a bottom-positioned legend for cross-platform comparison. The data is hardcoded in the script and reflects growth trends across the three social media platforms.
