You can totally do that with a CALayer
summary
Shows concrete CALayer techniques and limits: emitter layers, textLayer and transform3D, shape and gradient layers, and path interpolation that actually animate. Reports a real system with hundreds of thousands of data points and hundreds of layers rendering live, and fixes that by clip and filter points per screen point, using affine transforms to map data↔screen and by batching renders during gestures. Gives performance knobs like shadowPath and rasterization, simulator GPU artefacts, and path-point complexity thresholds.
