+.. title: Charts
+.. slug: charts
+
+If you are using reStructuredText and install pygal, Nikola has support for rather nice charts
+with little effort, and i's even semi-interactive (hover your pointer over the legend!):
+
+.. code:: rest
+
+    .. chart:: StackedLine
+       :title: 'Browser usage evolution (in %)'
+       :fill: True
+       :x_labels: ['2002','2003','2004','2005','2006','2007','2008','2009','2010','2011','2012']
+       :width: 600
+       :height: 400
+       :explicit_size: True
+       :style: BlueStyle
+
+       ('Others',  [14.2, 15.4, 15.3,  8.9,    9, 10.4,  8.9,  5.8,  6.7,  6.8,  7.5])
+       ('IE',      [85.8, 84.6, 84.7, 74.5,   66, 58.6, 54.7, 44.8, 36.2, 26.6, 20.1])
+       ('Firefox', [None, None, None, 16.6,   25,   31, 36.4, 45.5, 46.3, 42.8, 37.1])
+       ('Chrome',  [None, None, None, None, None, None,    0,  3.9, 10.8, 23.8, 35.3])
+
+.. raw:: html
+
+   <div style="text-align: center;">
+
+.. chart:: StackedLine
+    :title: 'Browser usage evolution (in %)'
+    :fill: True
+    :x_labels: ['2002','2003','2004','2005','2006','2007','2008','2009','2010','2011','2012']
+    :width: 600
+    :height: 400
+    :explicit_size: True
+    :style: BlueStyle
+
+    ('Others',  [14.2, 15.4, 15.3,  8.9,    9, 10.4,  8.9,  5.8,  6.7,  6.8,  7.5])
+    ('IE',      [85.8, 84.6, 84.7, 74.5,   66, 58.6, 54.7, 44.8, 36.2, 26.6, 20.1])
+    ('Firefox', [None, None, None, 16.6,   25,   31, 36.4, 45.5, 46.3, 42.8, 37.1])
+    ('Chrome',  [None, None, None, None, None, None,    0,  3.9, 10.8, 23.8, 35.3])
+
+.. raw:: html
+
+   </div>
+
+
+Here's how it works:
+
+* Next to the directive, use the `chart type you want <http://pygal.org/chart_types/>`_
+* Any option you can set in a chart? Use it like ``:title:`` in this example. Syntax on
+  the value is just like in the pygal examples.
+* For each data series do it like the line that says ``Firefox`` in this example. The first element
+  is the label, then comes the data.
+
+Easy, right? Please explore `the pygal site <http://pygal.org>`_ for more information, and just
+take this example and tweak stuff.
