The way I visualize numbers is actually based on a picture from my maths book in primary school. In that picture numbers were visualized as coloured, spiralling band / number ray with the integers from zero to 1000 written on it. The band started somewhere in the centre and spiralled rightwards and outwards from there. The funny thing is that I continued to use this image till today and for larger and more complex sets of numbers. Negative numbers for me are a continuation of the spiral to the left. For larger numbers the spiral continues to the right and in upwards in the 3rd dimension. Each number that's larger by an order of magnitude of 3 (10, 10000, 10000000 ...) roughly lies on the same 2-dimensional vector.
