{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"A D3.js scatter plot displays country-level COVID-19 data, plotting population density against median age for a dataset loaded from mergedata.json. The visualization uses d3.scaleLinear for both axes, d3.axisBottom and d3.axisLeft for gridlines, and d3.selectAll with data binding to render interactive circles. A tooltip, styled with CSS, appears on mouseover to show the country name, population density, and median age, while the circles change color on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4608aa269f2a418e89056391659c55b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
