The QGIS composer has an object for drawing and styling nonspatial shapes, including rectangles, ellipses, and triangles. In this recipe, we'll add some rectangles filled with different colors, which resemble a simple bar chart, as an example of using shapes.

Download the zipped shapefile for this map from https://github.com/GeospatialPython/Learn/raw/master/Mississippi.zip and extract it to your qgis_data directory in a subdirectory named ms.
We will also use the MapComposer library from https://github.com/GeospatialPython/Learn/raw/master/MapComposer.py, to simplify the creation of the map composition.
Place the file in the .qgis2/python directory within your home directory.
