+
+`Bokeh <https://bokeh.pydata.org>`_ is a Python interactive visualization
+library that targets modern web browsers for presentation. Its goal is to
+provide elegant, concise construction of basic exploratory and advanced
+custom graphics in the style of D3.js, but also deliver this capability with
+high-performance interactivity over very large or streaming datasets. Bokeh
+can help anyone who would like to quickly and easily create interactive
+plots, dashboards, and data applications.
+
+If you want to see some samples of bokeh's capabilities follow this `link
+<https://bokeh.pydata.org/en/latest/docs/gallery.html>`_.
+
+Installation
+============
+
+You need to install the python bokeh library::
+
+    pip install bokeh==0.12.7
+
+Usage
+=====
+
+To insert a Bokeh chart in a view proceed as follows:
+
+#. Declare a text computed field like this::
+
+    bokeh_chart = fields.Text(
+        string='Bokeh Chart',
+        compute=_compute_bokeh_chart)
+
+#. In its computed method do::
+
+    def _compute_bokeh_chart(self):
+        for rec in self:
+            # Design your bokeh figure:
+            p = figure()
+            line = p.line([0, 2], [1, 8], line_width=5)
+            # (...)
+            # Get the html components and convert them to string into the field.
+            script, div = components(p)
+            rec.bokeh_chart = '%s%s' % (div, script)
+
+#. In the view, add something like this wherever you want to display your
+   bokeh chart::
+
+    <div>
+        <field name="bokeh_chart" widget="bokeh_chart" nolabel="1"/>
+    </div>
