{"version":"1.0","type":"rich","title":"Sample Line Chart","description":"This sample line chart displays US GDP data from 1980 to 2020, drawing a smooth basis curve through the points. The code uses d3.scaleLinear for both axes, d3.axisBottom and d3.axisLeft for ticks, and d3.line with curveBasis to generate the path. It loads data from a CSV hosted on GitHub, parses the numeric values, and renders the chart as SVG with red strokes and a pink background. The title and axis labels are added via d3 text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de0af5a03ff14bb89d558f7bca874801?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
