{"version":"1.0","type":"rich","title":"Rapporto pcr/positivi per regione - line chart","description":"A line chart displays the percentage of positive PCR tests per day for a selected Italian region, using a dropdown menu to switch between them. The data comes from the Italian government's COVID-19 regional dataset, filtered to the last 90 days. Built with React and D3 v6, the SVG visualization uses `scaleTime` for the x-axis, `scaleLinear` for the y-axis, and `line` from d3 to draw the path, with circles and tooltips for each data point.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4068b29c5ffd4b148e1c9d06f73c7d5f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
