Geometries in MVT are just points, lines and polygons. These may be associated with zero or more key-values. The default 'viewport' (in SVG terms) is 4096x409

Geometries in MVT are just points, lines and polygons. These may be associated with zero or more key-values. The default 'viewport' (in SVG terms) is 4096x4096px, with geometries extending beyond this to allow for overlapping text labels, etc. SVG could represent anything MVT can -- but files would be much larger, as MVT is optimized to store the data efficiently.
