{"version":"1.0","type":"rich","title":"d3 implementation testing","description":"A scatterplot-style visualization maps four series of quarterly literacy and line-level scores as static steelblue circles, with each circle’s vertical position determined by its Q1 value. The chart uses d3.csv to load the dataset, d3.scaleLinear for both x and y axes, and d3.axisBottom plus d3.axisLeft to render the axes. All circles share a fixed radius of 20 pixels, and the SVG rendering is driven by standard d3 selections and data joins.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-12d0a71a14f4eb9d205ddfd2a4d2d92f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
