{"version":"1.0","type":"rich","title":"Tarea3","description":"This visualization displays student grades as individual data points plotted along a single quantitative axis. The scatterplot uses a linear x-scale with an oriented bottom axis, though the y-axis remains unused. The code loads grade data from an embedded array of objects and renders dots with stroke outlines. It relies on D3 v4 for the main visualization, while also loading D3 v3 for the axis and scale APIs, mixing both versions. The SVG rendering includes margin-based positioning and a placeholder text element, but no interactive features or additional encodings are implemented.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-2b9f00ac77b58d2d6d65a00666e5f60c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
