{"version":"1.0","type":"rich","title":"Acitivity6 ques 2","description":"This example visualizes population data for several countries across the years 1950-1955 using a stacked bar chart. The chart displays population counts on the x-axis and countries on the y-axis, with each bar segment representing a different year. Built with D3 v7 and rendered as SVG, it uses `d3.stack()` to compute the stacked series, `d3.scaleOrdinal` for color encoding, and includes interactive tooltips that display the population percentage for each year segment on mouseover. The data originates from a CSV file loaded locally.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/04f34aab9d284eb181f2e34f598eec47?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
