Building barplots in d3.js relies on the addition of several

<a href="graph/barplot_basic.html">first example</a> below should
guide you in this procedure. Note that
<a href="https://www.data-to-viz.com/caveat/order_data.html"
>ordering groups</a

is an important step when building barplots.
<a href="graph/barplot_ordered.html">This example</a> explains how to
do it.
