I am a newbie to Processing but am an experience programmer in a number of languages, including Java.

My problem relates to chapter 3 from the visualizing data book, where an image is dragged into the project along with a data file and an class called Table to read the data file.

When running the code I get the error:
Cannot find class or type named “Table”

Could someone possibly point me in the right direction.

The code I am using is copied from the book and shown below:

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

void draw(){
  background(255);
  image(mapImage,0 ,0);
 
  //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 = loationTable.getFloat(row,2); // column 2
    ellipse(x, y, 9, 9);
  }

The file has been down loaded and dragged into the sketch.
