### The underlying JavaScript code

```
JXG.serverBase = 'http://jsxgraph.uni-bayreuth.de/distrib/server/';
board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-2, 20, 20, -2], axis: true, grid: false, keepaspectratio: true});
p3 = board.createElement('point', [8, 3]);
p4 = board.createElement('point', [8, 8]);
c1 = board.createElement('circle', [p4, 4]);
p6 = board.createElement('glider', [0, 0, c1], {name:"D"});
g = board.createElement('line', [p3, p6]);
c2 = board.createElement('circle', [p6, 3]);
tracer = board.createElement('intersection', [c2,g,0], {name: "T"});
loc = board.createElement('locus', [tracer], {strokeColor: 'red', strokeWidth: '1px'});
