See this table   A 101x101 QR code  with high level error correction  can hold 3248 bits  or 406 bytes  Probably not enough for any meaningful SVG XML data   A 177x177 grid  depending on desired level of error correction  can store between 1273 and 2953 bytes  Maybe enough to store something small

QR codes have three parameters  Datatype  size  number of  pixels   and error correction level  How much information can be stored there also depends on these parameters  For example the lower the error correction level  the more information that can be stored  but the harder the code is to recognize for readers   The maximum size and the lowest error correction give the following values  Numeric only    Max  7 089 characters Alphanumeric    Max  4 296 characters Binary byte Max  2 953 characters  8-bit bytes
