If both are falsey, no web worker will be used. Otherwise, if useWorker is truthy, a dedicated web worker will be used. If the useSharedWorker option is truthy, a shared web worker will be used for the layout stage. The useWorker and useSharedWorker options If options is a boolean it is taken to be the useWorker option (for backwards compatibility). The others will keep their current values. Only the specified options will be changed. ¹ Only has effect when the graphviz renderer instance is created.Īll options are described below. All options except the useWorker and useSharedWorker options can also be changed later, using individual methods or the graphviz. If options is specified and is an object, its properties are taken to be options to the graphviz renderer. If a graphviz renderer instance already exists on that element, instead returns the existing graphviz renderer instance. Returns a new graphviz renderer instance on the first element in the given selection. The following table summarizes the recommended script type:Ĭreating a Graphviz Renderer Creating a Graphviz Renderer on an Existing Selection
This will work if a web worker is used and the drawNode and drawEdge functions are not used and will give shorter page load time. This will always work, but will not be optimal if the script is used in a web worker only. However, there are two d3-graphviz functions, drawNode and drawEdge that calls the layout functions directly and if they are going to be used, the script type must be "application/javascript" or "text/javascript". This is accomplished by using the script tag "javascript/worker" which the browser does not identify to be Javascript and therefore does not compile. In this case, it's unnecessary to let the browser also load and compile the script. If a web worker is used, these functions are called from the web worker which then loads and compiles the script explicitly. The script provides functions to do Graphviz layouts.

Uses to do a layout of a graph specified in the DOT language and generates an SVG text representation, which is analyzed and converted into a data representation. The built library will then be in build/d3-graphviz.js Principles of Operation
