{"version":"1.0","type":"rich","title":"Winter Olympics Participants - Iterate","description":"This visualization displays the number of participant countries in each Winter Olympics from 1924 to 2018, with each circle representing a year. The code computes participant counts by aggregating unique country names per year using a JavaScript `Set` within a `reduce` operation. It uses D3.js scales and axes to map years and counts, and renders circles with a fixed radius and reduced opacity to show the trend. Data comes from a Kaggle dataset of Winter Olympic medals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8976ad6891d46328203820106395504?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
