 With the same component, we can just as easily render a 4D map where the third dimension is the month and the fourth dimension is temperature or precipitation (labeled “band”). Pointing to this dataset, the `Raster` component becomes the following.

 In more advanced settings, we might want more control over rendering, including the ability to combine data across multiple layers with math. We've exposed a custom fragment shader prop `frag` to make this easy. In the sample below, we render the average temperature over January and February by loading both months at once and calculating the average on the GPU, followed by a rescaling and colormap lookup. While this requires writing [shader code](<https://www.khronos.org/opengl/wiki/Core_Language_(GLSL)>), it lets us combine data layers via arbitrarily complex math, with high performance and full control over what gets rendered. Here’s a `Raster` component that demos this approach.
