!!Attention!!

• In order to generate graphical output (such as PNG or SVG files), you must have Graphviz installed on your system. You can download and install it from Graphviz's Official Website. If Graphviz is not installed, the library will return a String containing the graph translated into the .dot graphic language instead of generating the PNG or SVG graphical output.

• When a PNG file is generated, the temporary file will not be automatically deleted. You need to manually manage or delete the file after using it.
