Demos

• Creating Excell graphs and tables
  1. Expected values when rolling many die produces this Excel spreadsheet
  2. Querying gender by major from prior learning survey produces this Excel spreadsheet.
• Creating graphics pictures
  1. Creating Fractals creates this ppm file. Which is this picture.
  2. Visualizing Primes creates this ppm file. Which is this picture.
  3. Creating a color palette creates this ppm file. Which is this picture.
  4. The shape libray allows one to draw pictures. Here is an example.
• Creating Music
  1. Dan Brown wrote Tubular bells. Listen here.

Libraries

The demos, and many of the exercise use some libraries. Here are the sources to the libraries. All you need to do is copy them into the directory where your Haskell files live.

• Colors for the graphics libraries, Colour.hs
• Jaap Weel's Comma separated values library, CSV.hs
• Excel table creation, Excell.hs
• PPM graphics file format. PPM3.hs and PPM6.hs
• Mark Jones' fractal library Fractals.lhs
• Mark Jones' region library Regions.lhs
