When it comes to the placing of tokens, I decided to only support single dots placed at the positions of data points. When using tokens, which are formed by multiple dots arranged in a texture like formation, the grid of the Braille embosser becomes a significant problem. As the minimum size of distinguishable tokens is 3x3 dots, each token would be split inevitably at the borders of different Braille cells of size 2x3 or 2x4. This would restrict their recognizability.

Due to the limitation to only one type of tokens (single dots), there can be only one data set per document. If the input data (from the CSV file) contains multiple data sets, each data set will be rasterized to a separate document.
