{"version":"1.0","type":"rich","title":"[A7] (Heat Map for Time Series Data with a Color Legend)","description":"This visualization displays a heat map of the Consumer Price Index for various grains (Corn, Rice, Rye, Wheat) from 2000 to 2015, using a sequential color scale from light to dark yellow-orange to represent CPI values. The example renders time series data as a grid of colored rectangles, with each column representing a year and each row a grain type, alongside a color legend and axes. It uses D3 v7 and the d3-legend library, implementing scales such as `d3.scaleLinear` for the year axis and `d3.scaleSequential` with `d3.interpolateYlOrBr` for coloring. Tooltips appear on mouseover to reveal the exact year, grain, and CPI value, while the data is loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fe4800804b6a4bb0ba108e4997d78874?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
