Trace the orbit of point `p` which depends "somehow" on a slider `s`. The simple method is to add the attribute `trace:true`. This invites exploration. If the trace curve should be used for further construction, the element `tracecurve` is useful.
// Define the id of your board in BOARDID
const board = JXG.JSXGraph.initBoard(BOARDID, {
boundingbox: [-1, 5, 9, -5], axis:true,
showClearTraces: true
});
var s = board.create('slider', [[1,-4], [7,-4], [0.01, 1, 8]]);
var p = board.create('point', [
() => s.Value(),
() => Math.log(s.Value())
], {trace:true});
var c = board.create('tracecurve', [s, p]);
