A python command-line tool which draws basic graphs in the terminal

$ python termgraph.py ex1.dat
I wanted a quick way to visualize some data which is stored in a simple text file. I initiall created some scripts in R which generated graphs but tended to be a two step process of creating the graph and then opening the generated graph.
I did some graphing using gnuplot, but X11 would never be started so it took time to start. So after seeing command-line sparklines I figured I could do the same thing using block characters for bar charts.
-
Create data file with two columns either comma or space separated. The first column is your labels, the second column is a numeric data

python termgraph.py [datafile]
I may or may not ever get around to these TODOs but a few ideas to take it further
- Add switch for vertical bar charts
- Add options and flags for width
- Add options for different colors
- Stacked Bar Charts
- Multiple series (side-by-side)
