{"version":"1.0","type":"rich","title":"2nd visual","description":"This bar chart shows the total COVID-19 cases reported in 2020 for five selected countries: the United States, India, Brazil, Russia, and the United Kingdom. It aggregates data from a CSV file hosted on GitHub, filtering records by year and location, then summing the `total_cases` field per country using `d3.nest()`. The visualization uses `d3.scaleBand` and `d3.scaleLinear` to position bars, with axes rendered via `d3.axisBottom` and `d3.axisLeft`. Interactive tooltips appear on mouseover, displaying the country name and its case count, while the SVG is animated only through these transition-based hover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fe649d5edb594f0bbce5f16c030ba1b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
