============

pygal is a SVG charting library written in python.

.. pygal:: 300 200

   chart = pygal.HorizontalBar(y_label_rotation=-25)
   chart.x_labels = 'one', 'two', 'three', 'four', 'five'
   chart.add('red', [1, 2, 3, 1, 2])
   chart.add('green', [4, 3, 0, 1, 2])

.. pygal:: 300 200

   chart = pygal.Line(x_label_rotation=25, fill=True, style=pygal.style.NeonStyle, interpolate='cubic')
   chart.x_labels = 'one', 'two', 'three', 'four', 'five'
   chart.add('red', [1, 2, 3, 1, 2])
   chart.add('green', [4, 3, 0, 1, 2])

.. pygal:: 300 200

   chart = pygal.Pie()
   chart.x_labels = 'one', 'two', 'three', 'four', 'five'
   chart.add('red', [1, 2, 3, 1, 2])
   chart.add('green', [4, 3, 0, 1, 2])

.. pygal:: 300 200

   chart = pygal.Radar(fill=True, style=pygal.style.NeonStyle)
   chart.x_labels = 'one', 'two', 'three', 'four', 'five'
   chart.add('red', [1, 2, 3, 1, 2])
   chart.add('green', [4, 3, 0, 1, 2])
