如何在neovis.js / vis.js中为一组节点制作统一的颜色

Question

我正在使用Neo4j应用程序。并创建节点图。为了在UI上显示节点图，我们有Neovis.js。 Neovis.js名称取自vis.js。我得到的输出是-

在图片中，所有节点的颜色都不同。我们具有部门，功能，系统，参数等关系。我希望所有具有关系的节点（参数）和所有具有关系的节点（部门）都具有统一的颜色。

请建议更改以下代码。这将非常有用。

Neovis.js中的

visjs

visjs: {
        interaction: {
            hover: true,
            hoverConnectedEdges: true,
            selectConnectedEdges: false,
    //        multiselect: true,
            multiselect: 'alwaysOn',
            zoomView: false,
            experimental: { }
        },
        physics: {
            barnesHut: {
                damping: 0.1
            }
        },
        nodes: {
            mass: 4,
            shape: 'neo',
            labelHighlightBold: false,
            widthConstraint: {
                maximum: 40
            },
            heightConstraint: {
                maximum: 40
            }
        },
        edges: {
            hoverWidth: 0,
            selectionWidth: 0,
            smooth: {
                type: 'continuous',
                roundness: 0.15
            },
            font: {
                size: 9,
                strokeWidth: 0,
                align: 'top'
            },
            color: {
                inherit: false
            },
            arrows: {
                to: {
                    enabled: true,
                    type: 'arrow',
                    scaleFactor: 0.5
                }
            }
        }

    }
