{"version":"1.0","type":"rich","title":"Activity6_Q4","description":"A bubble chart displays foreign exchange rates for multiple countries across two years (2016 and 2017), using bubble size and color to encode the exchange rate values along a categorical x-axis and a linear y-axis. The D3 v7 application imports data from a CSV file, sorts it by rate, and renders an SVG with axes, labels, and interactive tooltips. It uses `d3.scalePoint`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.schemeCategory10` for positioning, sizing, and coloring, with mouse events (`mouseover`, `mousemove`, `mouseleave`) showing detailed tooltip information.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f672e0abd1874d11b46b7baf89309359?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
