I have a collection of networks consisting of nodes and links stored in various JSON files. I am using D3.js to load them into a Force Layout, where they each load and layout perfectly when loaded individually. However, I would like to enhance the functionality by enabling users to load any of these network files on the same page one at a time, with the Force Layout resetting whenever a new network is loaded from its respective JSON file.
How can I restart the Force Layout upon loading a new network from a JSON file? The closest solution I found was http://bl.ocks.org/mbostock/1093130, but it only works for a single file.
Anomalies observed:
In my experiments with the Force Layout, I discovered an unusual behavior. When I quickly switch between JSON files every second, the Force Layout continues to lay them out correctly. However, if I wait more than a few seconds before switching, the Force Layout seems to settle on a final layout based on the second network and stops laying out subsequent networks thereafter.
Additional insights: Upon encountering issues with the Force Layout, I encountered an unexpected error message:
Uncaught TypeError: Cannot call method 'call' of undefined
This error seems to be internal to D3.js and arises within the following code snippet:
d3_selectionPrototype.each = function(callback) {
return d3_selection_each(this, function(node, i, j) {
callback.call(node, node.__data__, i, j);
});
};
