{"version":"1.0","type":"rich","title":"Lockdown Timeline","description":"This visualization displays a timeline of three pandemic lockdown events, using a horizontal axis to mark dates in March and December 2020. It encodes each event as a point on the timeline, with annotations providing the location and nature of the lockdown. The SVG is constructed with D3.js v7, using `d3.scaleTime` for the time axis, `d3.axisBottom` with custom tick values and formatting, and `d3.timeParse` to convert date strings. Annotations appear via appended SVG groups at calculated positions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/18d52f5975fb4e9584240bbbafcd3c29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
