{"version":"1.0","type":"rich","title":"Customizing axes","description":"This bar chart displays the population of Sub-Saharan African countries in 1950, using data from the United Nations World Population Prospects 2017. The visualization customizes both axes: the y-axis removes its domain and tick lines for a cleaner look, while the x-axis formats population values with d3’s `format('.3s')` and adds negative tick sizes to create gridlines. Built with d3.scaleBand and d3.scaleLinear, the chart renders as SVG rectangles with a steelblue fill and includes a title and axis label.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce7de7979a2b47fc822abf7b9c7b3bdb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
