{"version":"1.0","type":"rich","title":"Line Chart - Income","description":"This line chart displays average income by highest education level, from elementary school through doctorate degrees, using data from the U.S. Census Bureau’s Survey of Income and Program Participation. The visualization pairs a black polyline with colored dots at each data point, making the upward trend in earnings with advanced education clear. Built with D3 v4, it uses `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and `d3.line` to generate the path, while circles are added via `enter().append(\"circle\")`. The chart renders as SVG with axes from `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-92d6cd1d2a69831256097a7b624177ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
