{"version":"1.0","type":"rich","title":"piechart_linechart","description":"This example shows a line chart depicting the relationship between fuel efficiency and engine size for a car dataset. The SVG visualization uses D3.js v6 to load CSV data from a GitHub gist, parse numeric values, and render a single blue line path via `d3.line()`. Linear scales (`d3.scaleLinear`) map the fixed domains for fuel efficiency and engine size, while axes are generated with `d3.axisBottom()` and `d3.axisLeft()`. The chart includes labeled axes for fuel efficiency and engine size, with margins and dimensions set explicitly in the code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f9219b526794e7e87c34c97aa885eeb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
