{"version":"1.0","type":"rich","title":"Task 4","description":"This example presents a multi-line chart tracking total COVID-19 deaths over time for the first 20 countries in a filtered dataset. It loads data from a remote CSV file and uses D3 v6 to render SVG paths, with an ordinal color scale distinguishing each country and a legend identifying them. The code employs `d3.csv`, `d3.timeParse`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` to build the visualization. The rendering approach uses a standard SVG container with configured margins for axes and labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7ff662cacfd4be88a451c245856ea6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
