{"version":"1.0","type":"rich","title":"Issues Ratings","description":"The visualization shows how issue ratings change over time across many countries, with each country represented by a distinct colored line. The main chart plots yearly ratings, while a smaller brushable context view below enables zooming into specific time ranges. Data is loaded from a CSV file and processed using D3 v3. The implementation uses `d3.time.scale` for the time axes, `d3.svg.line` for the series, and an ordinal color scale with custom colors. A brush filter updates the main display based on the selected range.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d694ed4a132f4f268637f7fe78f5900d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
