{"version":"1.0","type":"rich","title":"Prototype v4","description":"This visualization shows Rhode Island's monthly unemployment rate (RIUR) from 1976 onward, highlighting historical spikes with red dots overlaid on a steelblue line chart. The React app loads data from a CSV file using d3.csv, parses dates with d3.timeParse, and renders the chart through d3.scaleTime, d3.scaleLinear, d3.line, d3.axisBottom, d3.axisLeft, and d3.extent functions. A legend distinguishes the line series from annotated spike points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/def0ce8f6aa14a3498734ba0b43b530e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
