{"version":"1.0","type":"rich","title":"Covid-19 Cases Analysis","description":"This interactive narrative visualization analyzes U.S. COVID-19 case trends across multiple scenes, beginning with a line chart of total confirmed cases from January to May 2020, followed by state-level comparisons and a geographic distribution map. The first scene uses D3 v7 with `d3.select`, `d3.csv`, `d3.timeParse`, and `d3.line` to render an SVG line chart, plotting dates against confirmed case counts from a public COVID-19 dataset. The visualization employs a slideshow navigation format with interactive elements for exploring different data aspects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba6e8d7127db45c3bb2cc50af80a6f2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
