{"version":"1.0","type":"rich","title":"Line Chart","description":"This line chart visualizes the total population estimates for Texas from 2020 to 2024, aggregating county-level data from the Census Bureau. The chart draws a smooth steelblue line with orange circles marking each year’s total. Built with D3 v7, the code loads a CSV via `d3.csv`, sums population columns using `d3.sum`, and renders the SVG with `d3.line`, `d3.curveMonotoneX`, and linear scales for the axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/429835442b47477db9f8982d41d3932f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
