The underlying JavaScript code

JXG.serverBase = 'https://jsxgraph.org/distrib/server/';
board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-2, 20, 20, -2], axis: true, grid: false, keepaspectratio: true});
p3 = board.create('point', [8, 3]);
p4 = board.create('point', [8, 8]);
c1 = board.create('circle', [p4, 4]);
p6 = board.create('glider', [0, 0, c1], {name:"D"});
g = board.create('line', [p3, p6]);
