{"version":"1.0","type":"rich","title":"3rd visualisation","description":"This example shows a grouped bar chart comparing coal consumption and greenhouse gas emissions across different years. Using D3.js v7, the code loads data from a CSV file, groups it by year, and renders steelblue bars for coal consumption alongside orange bars for emissions. The SVG chart uses d3.scaleBand for the x-axis and d3.scaleLinear for the y-axis, with d3.axisBottom and d3.axisLeft for tick marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95c2c6608b59428bb67bce7a06f94188?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
