Javafx ("Les_Misérables")

well i thought having i few followers on twitter ,could allow me to create a data viz of who follows who keeping in mind the twitter API rate limit ,which didn't work and i took some time building the viz with dummy data ,i had a try with  Les_Misérables network of characters from Victor Hugo novel. the data

all characters

I edited the data to remain with label "character name" , source node and target node,the number of the node corresponds with the characters name. i.e number 11 is Jean Valjean.

drawing the nodes

private void drawNodes(AnchorPane root,List lines){
    
         Point2D center_point = new Point2D(size * 0.5, size * 0.5);
 
          for(angle=0,counter=0;angle;=360;angle+=angle_stepsize,counter++){
            
            double sinValue = Math.sin(Math.toRadians(angle + startAngle));
            double cosValue = Math.cos(Math.toRadians(angle + startAngle));

            Point2D outer_point = new Point2D(center_point.getX() + size * 0.445 * sinValue, center_point.getY() + size * 0.445 *   cosValue);
            Point2D outer_major_point = new Point2D(center_point.getX() + size * 0.470 * sinValue, center_point.getY() + size *  0.470 * cosValue); 

            Circle node=new Circle(1);
            node.setFill(Color.WHITE);
            node.setId(String.valueOf(counter));
            node.setLayoutX(outer_point.getX());
            node.setLayoutY(outer_point.getY());

            text.setLayoutY(outer_major_point.getY());
            text.setWrappingWidth(15);

            root.getChildren().addAll(node,text);

            textOnMouseOver(text,root,lines);
        }
    }

}

NB:ignore the string tags cant get to remove them
