Customizing Axes

This example demonstrates how to customize chart axes in D3.js, using a scatter plot of automobile data (horsepower vs. weight) from a CSV file. It shows how to remove the default axis frame lines, add tick marks that span the entire plot area, and append clear axis labels and a title. The code uses D3 v5 APIs including `select`, `csv`, `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and `format`. The rendering is done using SVG within a React project, with all styling applied via external CSS classes.

Fork of Let's make a face with D3.js!

This example renders a yellow smiley face with animated eyebrows using D3.js. It builds the face with SVG primitives—circles for the eyes, rectangles for the eyebrows, and an arc path for the mouth—centered via a translated group. The code applies chained `transition().duration(2000)` calls to move the eyebrows up and down repeatedly. It uses `select` to access the SVG element and `arc` from the `d3` module to generate the mouth’s path, with dimensions and positions hardcoded. The animation runs on a 960×500 canvas.
