Draw 100 random points

        board = JXG.JSXGraph.initBoard('box', {originX: 10, originY:390 , unitX:380 , unitY: 380});
                
        function reload() {
            JXG.JSXGraph.freeBoard(board);        
            board = JXG.JSXGraph.initBoard('box', {originX: 10, originY: 390, unitX: 380, unitY: 380});            

            board.suspendUpdate();
            for (var i=0;i<100;i++) {
                var p = board.createElement('point',
                       [Math.random(),Math.random()],{style:5,name:' '});
            }
            board.unsuspendUpdate();
        }
        reload();

Draw 100 random points

These 100 points are updated on the onmouseover event and get new random coordinates.
