{"version":"1.0","type":"rich","title":"Fork of Hello VizHub","description":"This visualization displays merged time-series data for COVID-19 cases and accident counts from two Google Drive-hosted CSV files, showing both trends as smooth lines in a single SVG chart. Using D3 v7’s `d3.csv` for data loading, `d3.timeParse` for date conversion, and `d3.scaleTime` with `d3.axisBottom` and `d3.axisLeft` for axes, the code merges records by date and draws lines with `d3.line` and `d3.curveMonotoneX`. The steelblue line represents COVID cases while the green line shows accidents, with data processed through a `Promise.all` merge and local ES6 modules.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/afe23c0469e14afb8c9b561398573cee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
