{"version":"1.0","type":"rich","title":"TINTIN SPAC trend","description":"This visualization shows the trend of SPAC and IPO activity in the US over time, using stacked bars to compare counts by type. The chart encodes the year on the x-axis and the summed IPO count on the y-axis, with color distinguishing SPAC from IPO types. It is built using the vega-lite-api, which registers vega and vega-lite, and loads CSV data via d3.csv. The bar marks are rendered with SVG, and appearance is customized through a configuration object for axis styling and tooltip settings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eee0d4bd30d3470f8e13194ae0084c1b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
