Portfolio Assignment 8

Creating a Simple Visualization

Task: Generate a dendrogram and a 2D cluster diagram (using multidimensional scaling)

Chapter 3 of our Collective Intelligence book includes two examples of visualization. Your assignment is to generate the graphics using the provided code examples as a guide.

Specific Tasks

For this assignment, focus on generating the graphics files.

1. Implement the drawdendrogram() function and create a jpg image from the clusters in assignment 7.
2. Implement the draw2d() function and create a jpg image similar to figure 3-10.
3. In your own words, explain the multidimensional scaling technique used in the scaledown() function. (See p49 - 50.)
