This visualization shows the relationship between daily temperature and ice cream sales, plotting each data point as a dot on a scatterplot and connecting them with a line to highlight the upward trend. The line and circles are rendered in SVG using D3 v3, with sales rising as temperature increases. The code uses d3.csv to load the data, d3.scale.linear for the x and y axes, and d3.svg.line plus circle elements to draw the chart, with both axes oriented and ticked via d3.svg.axis.
