I have a lot of basic questions about the CVVDP graph. Is the X axis encoding or decoding speed? Is higher better on the Y axis? What format is Aperture? I assume "aom" is AV1 but it wouldn't hurt to document it.

x-axis is encoding speed, Y-axis is BD-rate where higher is better. aperture-alpha is an upcoming encoder from Halide Compression, no more details than that. libaom and SVT-AV1 are both for AVIF; libaom is the AV1 reference encoder.
