{"version":"1.0","type":"rich","title":"Cigarette taxes by state, 1970-2014","description":"This visualization shows how cigarette sales taxes per pack as a percentage of retail price changed across U.S. states from 1970 to 2014, using data from the Centers for Disease Control and Prevention. A multi-series line chart rendered in SVG with D3 v3 displays one line per state, with each line encoding the tax burden over time. Oregon is highlighted in steel blue, while hovering over any line highlights it in orange and reveals the state name via a tooltip. The x-axis spans the years 1970–2014, and the y-axis shows the tax percentage, making it easy to compare tax trends across states over four and a half decades.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-a38204af9e258275cd8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
