<hr>
<p>D3.js offers built-in function to add axis to your chart. The first step is to build a <code>scale</code> that allows to transform a numeric value to a coordinate on the plot. The second is to call <code>axisBottom()</code> or <code>axisLeft()</code> to build the axis. Browse the example below to understand the different <u>types</u> of existing scale, how to <u>build axis</u> and how to <u>customize</u> them.</p>
