{"version":"1.0","type":"rich","title":"Polished Area Chart (don activity)","description":"This interactive area chart displays monthly Croatian Red Cross donation activity, aggregating total donations and isolating COVID-19 contributions. Users switch between viewing total, COVID-19, or other purpose categories via a custom menu. The visualization uses React with D3’s `scaleTime` and `scaleLinear` to render SVG areas, with a stripe-pattern mask distinguishing the COVID-19 subset. Data comes from a CSV file loaded via D3’s `csv` and `useData` hook, with axes built through reusable components.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0247bc8064114e6daed4baf360288c0a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
