{"version":"1.0","type":"rich","title":"Fork of Let's make a Bar Graph with D3.js","description":"A bar chart displays population data for ten countries, sourced from a CSV file, with each bar’s height encoding the numeric population value. Hovering a bar triggers a smooth color transition from green to blue via D3’s transition system. The visualization is rendered as an SVG using d3.scaleBand for the x-axis categories and d3.scaleLinear for the y-axis, while the mouseover and mouseout event handlers update the fill attribute. The animation is powered by D3’s transition API, and the chart dimensions are defined by chart_width and chart_height.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a1e236efdb454eefbc162ead325f5f1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
