{"version":"1.0","type":"rich","title":"Prototype v2","description":"This line chart tracks Rhode Island’s monthly unemployment rate from 1976 onward, using data from FRED. It plots the rate over time with a steel-blue line, while red dots flag five notable spikes, including the 2020 peak. The visualization is built with D3.js and React, using `scaleTime` and `scaleLinear` for axes and a custom binary search for hover tracking. A tooltip showing exact values appears on mouseover, and grid lines and axis labels support reading the trend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/333ffd9bef344d4788cffce567ed7f93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
