This line chart shows the average monthly high and low temperatures in San Jose del Monte, converted from Fahrenheit to Celsius and smoothed with a curve. Red and blue lines represent the high and low temperature trends across the twelve months, with a title and labeled axes. Built with d3.v7, the visualization uses `scaleBand`, `scaleLinear`, `line` with `curveBasis`, and `axisBottom`/`axisLeft` to render an SVG. The data originates from a WeatherSpark CSV file comparing two cities, and the chart includes gridlines and hover styling for the temperature values.
