Hey Pointc.
My idea is create a <img> inside a wrapper and animate the pizza, so it's a DOM animation.
So probably it's kind of "static" content.
I had an example to animate bars.
var timeline = new TimelineLite({ paused: true }),
$chart = $('.su__comp-chart'),
$x_axis = $chart.find('.su__chart-x-axis'),
$y_axis = $chart.find('.su__chart-y-axis'),
$axis_labels = $('.su__chart-axis-label'),
$bar_1 = $('#su__chart-bar-1'),
$bar_2 = $('#su__chart-bar-2');
timeline
.staggerFrom($axis_labels, 0.5, { opacity: 0 }, 0.1)
.add([
TweenLite.fromTo($bar_1, 2, { height: '1%' }, { height: '56%' }),
TweenLite.fromTo($bar_2, 2, { height: '1%' }, { height: '54%' })
]);
And them play.
timeline.play();
