{"version":"1.0","type":"rich","title":"FEM: Exercise 2 Line","description":"This line chart displays daily temperature readings for New York, San Francisco, and Austin from October 2011 through January 2012, using data from a tab-separated file. Each city is represented by a colored line, plotted over time with D3 v4’s scale functions for the time-based x-axis and linear y-axis. The visualization includes an interactive legend that toggles city lines on and off, with a smooth transition when data is filtered. The chart renders as SVG and uses axes, gridlines, and a hover tooltip showing the date and temperature values for each city.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e24820ee91c0ae4c66612ec7607fe6f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
