{"version":"1.0","type":"rich","title":"Line Chart","description":"This line chart displays annual U.S. auto sales by brand, with the x-axis mapping the year and the y-axis showing total sales volume. The visualization uses D3 v5's `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while the `line` generator draws the trend line. Data is loaded from a CSV file via `d3.csv`, and the chart is rendered as an SVG with styled gridlines and axis labels. The title \"Sales of the item at the time\" appears above the plot.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f4b150c8cdc148b792013cb776cee862?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
