{"version":"1.0","type":"rich","title":"2018: Smiley Face","description":"This example visualizes a timeline of tweets as a scatterplot, where each tweet’s vertical position reflects its impact (number of favorites) and its horizontal position reflects the time it was posted. Circle size and color also encode impact, using a linear scale for both radius and a color range from white to purple. The visualization uses D3 v5 to load the tweet data, map time with `d3.scaleTime`, and map impact with `d3.scaleLinear`. It renders circles and text labels as SVG elements, then filters out tweets with zero impact by removing their corresponding nodes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2fbdbbddf8843f196c06aacc77221e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
