This area chart displays the average monthly high and low temperatures for San Jose del Monte, converted from Fahrenheit to Celsius. The visualization uses filled paths to show both temperature ranges, with red representing high temperatures and blue for low temperatures, across the twelve months of the year. Data originates from weatherspark.com, processed through the d3.csv function. The chart uses d3.scaleBand for the x-axis and d3.scaleLinear for the y-axis, with d3.area and curveBasis to generate the smooth area paths rendered as SVG.
