{"version":"1.0","type":"rich","title":"SPAC IPO Counts and Proceeds Stacked Bar Charts","description":"This interactive visualization displays SPAC IPO counts and proceeds as stacked bar charts, with bars segmented by company and colored by mission status. A dropdown menu lets users switch the x-axis attribute between company name, country, or rocket status. The chart is rendered using the vega-lite-api library with vega-lite and vega, while React manages the UI state and dropdown interactions. Hovering over bars reveals tooltips with mission counts, and the data comes from a CSV file containing IPO counts, proceeds, year, and type information.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ce6d594ca7f474e80871e5c97167664?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
