{"version":"1.0","type":"rich","title":"A5-Line Chart","description":"This line chart displays the average horsepower of cars over time, with each point representing the mean value for a given year. The data is loaded from a CSV file hosted on GitHub Gist using `d3.csv`. The visualization uses D3 v6's `scaleLinear` for both axes, applies a monotone curve to smooth the line, and renders the chart as an SVG. Axis labels and a title are added with standard D3 axis functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9dc11e2b21534cb0942f0e9a96e47d14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
