{"version":"1.0","type":"rich","title":"Lab2-4","description":"This bar chart displays the population of the top 10 most populous countries, with data from the 2018 estimate in the United Nations World Population Prospects 2017. It builds on a prior bar chart by customizing axes, including tick formatting that converts large numbers to abbreviated forms like \"G\" for billions. The visualization uses D3 v5 APIs such as `csv`, `scaleLinear`, `scalePoint`, `axisLeft`, and `axisBottom`, rendering circles in SVG. Population values are multiplied by 1000 in the data-loading step, and the chart includes labeled axes and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d97554b1f1a49ea8c3d0825483a82c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
