Each state is represented by a colored line with a corresponding label at the right edge. Using d3.line, d3.scaleLinear, and d3.axisBottom/axisLeft, the SVG renders population trends. A mouseover tooltip reveals yearly totals and ranks states by population, with a vertical guide line using d3.mouse and d3.event. Data comes from the state-populations.json file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3b0d34e8b194647a57667a79419014d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
