2c:null 2d:["$","title",null,{"children":"groupedGraph | Kalle Westerling | Observable"}] 32:T903,In order to produce a graph, you need to run the function `groupedGraph`, and access its `.node()` method. The reason for this is for you to receive an `svg` node as a result from the function, which you can continue to build on. The `graph` data, as an object, is passed as the first argument to `groupedGraph`. Other variables that you can pass in to the visualization function includes: - `height`: in pixels, how tall do you want the rendered SVG element to be? - `color`: a [d3 scale](/@d3/color-schemes) which provides the coloring of the nodes. - `margin`: percent expressed as decimal, how far away from the nodes that the group border should be rendered, for example 110% = 1.1. - `curve`: a [d3 curve type](https://github.com/d3/d3-shape#curves) which provides the shape of the curves rendered around grouped nodes. - `onHover` and `onClick`: here you can provide functions that accept d3's regular arrow functionality, declaring what you want to happen when hovering and clicking respectively on nodes. _Note: See below for an example to clarify._ - `groupX` and `groupY`: a list of x and y values respectively (expressed in pixels on the SVG) where you'd like each group's gravity to pull towards. (Note that the number of entries in the list must match the number of groups, and that groups should start numbering at zero—alternatively keep the zero entry of the list empty.) _Note: you can try different settings for `margin` and `curve` in the visualization above._ Here is a summary of the function's settings, and its default values: ```js groupedGraph( { nodes: [], links: [] }, { height: 600, color: d3.scaleOrdinal().range(["red", "green", "blue", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]), margin: ${margin}, curve: "${curveType}", onHover: undefined, onClick: undefined, groupX: [], groupY: [], groupColorNames = [], r = 5, // accessor function or integer label = undefined, labelStyle = { fontFamily: "sans-serif", fontSize: 10, color: true }, strokeWidth = (d) => Math.sqrt(d.value), // accessor function or integer onLeave = undefined, displayGroupOnHover = false, chargeStrength = undefined, linkStrength = undefined, excludeGroups = [], fade = true } ) ```33:T1ed3,groupedGraph = ( graph = {}, { height = 600, color = d3 .scaleOrdinal() .range([ "red", "green", "blue", "#6b486b", "#a05d56", "#d0743c", "#ff8c00" ]), groupColorNames = [], margin = 1.2, curve = "curveCatmullRomClosed", r = 5, label = undefined, labelStyle = { fontFamily: "sans-serif", fontSize: 10, color: true }, strokeWidth = (d) => Math.sqrt(d.value), strokeStyle = { color: "gray", opacity: 0.6 }, nodeStyle = { stroke: "white", strokeWidth: "1.5px" }, groupStyle = { fillOpacity: 0.1, strokeOpacity: 1 }, onHover = undefined, onClick = undefined, onLeave = undefined, groupX = [], // in development groupY = [], // in development displayGroupOnHover = false, chargeStrength = undefined, linkStrength = undefined, excludeGroups = [], fade = true } = {} ) => { if ( !Object.keys(graph).includes("links") || !Object.keys(graph).includes("nodes") ) throw new Error( "The visualization must be provided a graph object containing links and nodes." ); if (graph.links.length === 0) throw new Error( `No links were provided.
