{"version":"1.0","type":"rich","title":"Multiline","description":"This interactive multi-line chart shows annual average temperatures across four continents (North America, Europe, Asia, Africa) from 2010 to 2019. Built with D3 v7, it uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for tick marks, and `d3.line` to generate the SVG paths. A `d3.schemeSet2` color palette distinguishes each series, with a legend rendered as colored circles and labels. Data comes from the local `global_temperature.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f60924c9dc654195b0a8da583a68a6ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
