configure node colors using %%graph_notebook_vis_options for RDF/SPARQL models

Hello,

The %%sparql magic in Neptune Notebooks comes with a suite of options that can be used to customize your query visualization. You can find more information about these options by running %%sparql with the --help option and anything in the cell body:

%%sparql --help
x

The --group-by option would be the most useful in regards to your question. When specified with any custom attribute name, --group-by will color the visualized nodes based on the value of the attribute.

For example, if you wanted to create color groups on the value of the attribute node attribute value, run:

%%sparql --group-by value
...

You also have the ability to choose a different attribute to group by for each node type. This can be done by first defining the groups in an empty cell:

groups = '{"uri":"value","identifier":"type"}'

Then using the Jupyter line variable injection syntax to assign the variable value to --group-by:

%%sparql --group-by $groups
...
