Currently, I am working with a force-directed graph and I would like the ability to switch between different JSON files dynamically, consequently altering the data displayed in the graph.
While I can manually change the file name in the HTML code, my goal is to achieve this asynchronously for a more seamless user experience.
I have explored options such as AJAX and XHR (XMLHttpRequest), but I am uncertain about how to begin implementing it.
It has been brought to my attention in the feedback that this is a broad inquiry, so here is a comprehensive response: If you are utilizing d3.json, you may be dealing with code similar to this:
d3.json("graphdata1.json", createMyGraph);
Alternatively, you can use a string variable to store the filename and make modifications as necessary:
var graphFilename = "defaultGraph.json";
// A certain process generates a different filename based on a selector resulting in something like
graphFilename = "newGraphData.json";
d3.json(graphFilename, createMyGraph);
If you wish to transition from one drawn graph to another, this entails a more elaborate procedure (and a separate query) involving .enter() and .exit() methods along with update behavior.
