This example visualizes a scatter plot of the Iris Dataset, showing the relationship between temperature and humidity for individual data points. The plot uses D3 v3 to generate SVG circles positioned by linear scales, with labeled axes for both variables. The code loads data from a CSV file via `d3.csv`, then maps numeric values to screen coordinates. The scatter plot demonstrates a reusable chart pattern from `scatterPlot.js`, which exposes configurable accessors and dimensions through a closure-based API.
