I would like to provide better visual segregation between nodes in Neo4j's web explorer. Is it possible to change the grass styles to allow for a square-shaped node? Below is an example of the node style I would like to alter. Is this possible within Neo4j or must an outside visualization library be used?
node {
diameter: 40px;
color: #DFE1E3;
border-color: #D4D6D7;
border-width: 2px;
text-color-internal: #000000;
caption: '{id}';
font-size: 10px;
}
