{"version":"1.0","type":"rich","title":"Fork of Hello VizHub","description":"This scatterplot visualizes NO2 mean levels over time using air pollution data loaded from a GitHub-hosted CSV. The view uses an SVG with D3 v7 to render blue circles for each data point, with time-based x-axis and linear y-axis. Code demonstrates D3’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` for chart construction, plus mouseover tooltips via D3 selections. The example also showcases importing D3 via UNPKG and local ES6 modules, as in the original Hello VizHub template.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/070a684a2713476c9068dc566d29d3f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
