{"version":"1.0","type":"rich","title":"Vega-Lite API Template for  Udemy Course","description":"This visualization shows the relationship between course publication date and subscriber count for Udemy courses, revealing that publication timing has little correlation with subscription numbers. The scatterplot uses Vega-Lite API through d3.v5, with data loaded from a CSV via d3.csv. The visualization applies configurable styling and tooltips via vega-tooltip, with points sized and opacity-adjusted to show density at overlapping coordinates. Both axes use zero-disabled scales for clearer distribution analysis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a05c0f264bd446c7ad26567693b3fdbd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
