Uncaught TypeError in Rotating Voronoi Example

[kahunamoore]

Uncaught TypeError: Cannot read property 'x' of null

The call stack looks like this:

Uncaught TypeError: Cannot read property 'x' of null tr @ d3.v3.min.js:2 Ze @ d3.v3.min.js:2 ar @ d3.v3.min.js:2 t @ d3.v3.min.js:4 (anonymous function) @ rotating-voronoi.js:25538 Rn @ d3.v3.min.js:1 Tn @ d3.v3.min.js:1

The minimized version of the code looks like this (in rotating-voronoi.js:25538):

strokes.timer.call(null, function() { var pts_5281 = rotating_voronoi.get_points.call(null); var vnoi_5282 = rotating_voronoi.vor_obj.call(null, pts_5281); // <--- ERROR IS IN THIS CALL (lineno: 25538) rotating_voronoi.circles.attr("transform", function(p15280SHARP, p25279SHARP) { return[cljs.core.str("translate("), cljs.core.str(cljs.core.nth.call(null, pts_5281, p2__5279SHARP)), cljs.core.str(")")].join("") }); rotating_voronoi.path.attr("d", function(pt, i) { return rotating_voronoi.line.call(null, rotating_voronoi.resample.call(null, cljs.core.nth.call(null, vnoi_5282, i))) }); return false });
