Use Gnuplot and the data from autoData.txt to generate separate bar graphs for the following:

• The ”MidPrice” of all the ”small” cars.
• The average fuel consumption (MPG - miles per gallon) for all the ”large” cars.
• The ”MaxPrice” over the average fuel consumption for all ”chevrolet” and ”ford” cars.

The graphs should be as complete as possible (title, axes names, etc.)
