{"version":"1.0","type":"rich","title":"Barchart","description":"This visualization displays iPhone sales data as a set of grouped bar charts, with each chart representing a different year and bars showing sales figures across countries. The code uses D3 v7 to fetch data from a CSV file, then creates separate SVG charts per year, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the quantitative y-axis. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, while hover effects change bar fill color to orange via CSS. The rendering approach is SVG, with a clean layout featuring dashed gridlines and clearly labeled axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d0e430ca58f94feea8f856ef667fe407?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
