This scatter plot visualizes global temperature changes from 1880 to 2016, with each green circle representing the annual mean temperature deviation recorded by either the GCAG or GISTEMP source. The visualization uses d3.scaleLinear for both axes, d3.axisBottom and d3.axisLeft for tick marks, and d3.csv to load the dataset. SVG circles are positioned using the x and y scales, with a title and axis labels rendered as text elements.
