{"version":"1.0","type":"rich","title":"Task4","description":"This bubble chart visualizes the correlation between the number of goals scored, the year, and attendance for FIFA World Cup tournaments from 1930 to 2014. Each circle represents a tournament, with its x-position indicating the year, y-position showing the average goals scored, and radius scaling with attendance. The chart uses D3.js v7 with SVG rendering, employing `scaleLinear` for axes and bubble size, `scaleOrdinal` for color mapping, and `interpolateTurbo` for the color palette. Interactive tooltips display the country name on hover, with animated transitions for showing and hiding the tooltip. The visualization includes a legend for attendance values and color-coded country labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0454978cc6ee4f2bb09ee64bde28d72a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
