1. When I try to run CViz, a DOS window pops up momentarily and then nothing happens. Or I see the message "the name specified is not an internal or external command." What's wrong?
On Windows, you must have the program jre.exe (Java Runtime Environment) installed on your machine in order to run CViz. The program must also be in your path. Try typing "jre" in a DOS window to see if this is the case in your environment.
On Unix, you must have the program "java" installed on your machine and in the path.
3. Once the CViz window comes up, what do I do next?
Load in a data file. Click on the File menu in the menu bar and select Open Data File.... Then select a data file to open. Two example files are provided: housing.csv and iris.csv.
The most common data format given to CViz is comma-seperated value. The first row of the file should contain the column names separated by commas. The remaining rows contain one example data point each. The examples should be represented as floating point numbers separated by commas. Categorical values are also allowed. These must be represented as non-numeric strings. Columns should be either all categorical or all numeric.
Examples of this data format are given in the files housing.csv and iris.csv.
