<p>This module adds the possibility to insert mpld3 charts into Odoo
standard views. This is an interactive D3js-based viewer which brings
matplotlib graphics to the browser.</p>
<p>If you want to see some samples of mpld3s capabilities follow this
<a class="reference external" href="http://mpld3.github.io/">link</a>.</p>

<p>To insert a mpld3 chart in a view proceed as follows:</p>

<pre class="literal-block">
_name = 'res.partner'
_inherit = ['res.partner', 'abstract.mpld3.parser']

</li>
<li><p class="first">Import the required libraries:</p>
