{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows the cumulative running total of a dataset from 1884 to 2010, with values increasing from 1 to over 160,000. The visualization renders as a solid red rectangular SVG area, though the code does not yet plot the data points. It uses D3 v6.5.0 to select the SVG element and apply a background color via inline styling. The data is loaded from a CSV file containing two columns: year and running_total. The page includes a tutorial video and basic setup for a homework assignment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/77e934f30e0841d197d3a8183a7d8706?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
