{"version":"1.0","type":"rich","title":"Coronav deaths over time by country (linear)","description":"A multi-line chart tracks cumulative COVID-19 deaths over time for each country, with one colored path per nation. The visualization uses a linear y-scale and a time-based x-axis, with gridlines and axis labels formatted via `d3.axisBottom` and `d3.axisLeft`. Data is loaded from a CSV using `d3.csv` and parsed with `d3.timeParse`. The React component builds an SVG, generating paths with the `d3.line` generator and rendering axes through custom React hooks that forward refs to D3 selection calls.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/937f0dfc88384c499bddc5756abb1fc2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
