== Visualizing data with Matplotlib and Wiki-bios ==

In this session, we will explore how to produce clear, informative charts, graphs, and plots with [http://matplotlib.org/ Matplotlib], the most popular toolkit for scientific data visualization in Python.

We'll start with the data-set created in [http://wiki.communitydata.cc/Community_Data_Science_Workshops_(Spring_2015)/Day_3_Lecture this morning] containing information about edits to the Harry Potter Wikipedia article. 

We will then proceed to visualize different aspects of data from the [http://wiki.communitydata.cc/Community_Data_Science_Workshops_(Spring_2015)/Day_2_Projects/Socrata Socrata web API].


=== Goals ===

* Get set up to make graphs with Matplotlib
* Learn the basics of the Matplotlib API and workflow
* Practice reading the Matplotlib documentation
* Build a plotting program step by step
* Learn simple ways to distill the essence of a large data set
* Explore the art of visualizing data
* Exercise your creativity by making your own visualization

# Download the CDSW Matplotlib code from [[http://mako.cc/teaching/2015/cdsw-autumn/wikibios.zip here]] 
# First plot: `001-hello-plot.py`
# Subplots: `002-subplots.py`
