To insert a mpld3 chart in a view proceed as follows:

#. Import the required libraries::

    import matplotlib.pyplot as plt, mpld3

#. Declare a text computed field like this::

    mpld3_chart = fields.Text(
        string='Mpld3 Chart',
        compute='_compute_mpld3_chart',
    )

#. In its computed method do::

    def _compute_mpld3_chart(self):
        for rec in self:
            # Design your mpld3 figure:
            plt.scatter([1, 10], [5, 9])
            figure = plt.figure()
            rec.mpld3_chart = mpld3.fig_to_html(figure)

#. In the view, add something like this wherever you want to display your
   mpld3 chart::

    <div>
        <field name="mpld3_chart" widget="mpld3_chart" nolabel="1"/>
    </div>
