It renders grouped bar charts for each country-year combination, with axes, dashed grid lines, and hover tooltips to highlight values. The code uses D3 v7’s `d3.csv`, `d3.scalePoint`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.schemeCategory10` for color encoding, producing an animated SVG view of economic changes over time.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a53f242b86764de6928209222fc291b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
