The underlying JavaScript code

JXG.Options.line.strokeWidth = 0.8;
var board = JXG.JSXGraph.initBoard('jxgbox', { boundingbox: [-5, 5, 5, -5], axis: true, showClearTraces: true});
var O = board.create('point', [0,0], {name: 'O', fixed: true});
var k0 = board.create('circle', [O, 4], {fixed: true, strokeWidth: 0.8});
var k1 = board.create('circle', [O, 2], {fixed: true, strokeWidth: 0.8});
var B = board.create('glider', [2.65, 3, k0], {name: 'B'});
var li = board.create('line', [O, B], {straightFirst: false});
var g = board.create('parallel', [B, board.defaultAxes.x]);

var pol = board.create('polygon', [O, X, P, Ps, B], {fillColor: 'yellow'});
