For crochet designers who would like to provide charted instructions in addition to the written instructions.
Options for chart creation:
entire design in one chart for designs with only a few rows/rounds
portions of the design in multiple charts to correspond to pattern sections
colour choice for each row/round
key/legend to chart symbols included, separately or positioned with chart
chart(s) available in multiple formats (pdf, png, jpg, svg)
time required to create a crochet chart depends on the complexity of the design
