I'm new at the language and just began working with the Visualizing Data book written by Ben.

 

On page 33, I have typed the code into the Processing window and when I click run, I receive this message:

Cannot find a class or type named "Table"

 

The code is as it is in the book - no typos. Here is the code - if someone can help me out, I'd be grateful.

Thanks - Brian

 

PImage mapImage;
Table locationTable;
int rowCount;

 

void setup(){
  size(640,400);
  mapImage = loadImage("map.png");
  //Make a data table from a file that contains
  //the coordinates of each state
 
  locationTable = new Table("locations.tsv");
 
  //The row count will be used a lot, so store it globally
  rowCount = locationTable.getRowCount();
}

 

void draw(){
  background(255);
  image(mapImage,0,0);
//Drawing attributes for the ellipses
  smooth();
  fill(192,0,0);
  noStroke();

//Loop through the rows of the locations file and draw the points
for(int row = 0; row < rowCount; row++){
  float x = locationTable.getFloat(row, 1); //column 1
  float y = locationTable.getFloat(row, 2); //column 2
  ellipse(x,y,9,9);
 }
}
