+#### Type
+
+Option: `type`\
+Values:
+
+1. `type_types.braille`: Braille (default)
+2. `type_types.block`: Block
+
+The Braille type has the highest resolution of 2×4 pixels per character, while the block type uses 2×2. This option is only used for plots and graphs. Histograms use 1×8 pixels per character.

+Values:
+
+1. `mark_types.dot`: Dot (default)
+2. `mark_types.plus`: Plus
+3. `mark_types.square`: Square
+
+The dot mark type uses a single pixel per mark, the plus uses five pixels and the square uses eight pixels. This option is only used for plots and graphs.
