{"version":"1.0","type":"rich","title":"United State GDP","description":"This D3.js v4 visualization displays the quarterly gross domestic product of the United States from 1947 to 2015 as a series of vertical bars. An interactive tooltip reveals the exact date and GDP value in billions of dollars for each quarter. The chart uses `d3.scaleTime` for the x-axis, `d3.scaleLinear` for the y-axis, and `d3.axisBottom` and `d3.axisLeft` to render the axes. Data is sourced from the FreeCodeCamp GDP-data JSON file hosted on GitHub. Animated transitions enhance the tooltip and overlay effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8dcf41a6ca3b4ddcaa6372cdfbb41dc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
