Using table columns for metadata and styles
As mentioned above, you don’t need to display every column of your CSV table in your diagram. Some of these columns can be used as metadata, or instructions for how to format a shape. For example:
# style: label;image=%image%;whiteSpace=wrap;html=1;rounded=1;fillColor=%fill%;strokeColor=%stroke%;
The columns image, fill and stroke are used to set the style of the shape – the image that is used and the color of the lines and background. We don’t want to display their text in the shape itself, so we have another configuration option to ignore them when drawing the shape. We also ignore the id column, as it is used as the target for the ref connectors.
# ignore: id,image,fill,stroke
