{"version":"1.0","type":"rich","title":"LineChart","description":"This line chart visualizes earthquake statistics from 2000 to 2015, comparing the annual frequency of earthquakes across different magnitude ranges (5–5.9, 6–6.9, 7–7.9, and 8.0+) as four distinct colored lines. Built with D3 v5 and rendered as SVG, it uses `scaleTime` and `scaleLinear` for axes, `d3.line` with `curveBasis` for smooth paths, and `axisBottom`/`axisLeft` for gridlines. Data is loaded from a CSV via `d3.csv`, with the chart including a legend and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f1353f493d047c9b8db4ba988a8b0c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
