I want some of the nodes in my force-directed layout to ignore all forces and stay in fixed positions based on an attribute of the node, while still being able to be dragged and exert repulsion on other nodes and maintain their link lines.   I thou...
I am trying to add text label to nodes in d3 Force Directed Graph, there seems to be an issue. This is my Fiddle:    When I add the node name like this:  node.append("text")     .attr("class", "word")     .attr("dy", &...
I have a graph using force layout, but it has a fixed width w and height h:  var svg = d3.select("#viz").append("svg")             .attr("id", "playgraph")             .attr("width", w)             .attr("h...
I have developed a force layout to represent relationships between social groups. Now I would like to get the nodes to be distributed in a circle with links joining them. What is the best way to do this?   The complete version of the code (without da...
I believe I found a bug in D3 v4.x (v4.5.0), when in a force-directed chart one combines d3.forceCollide to prevent nodes from overlapping and d3.forceX/Y to set the position of the nodes with a high strength value, and I’m about to create an issue...
Here is jsfiddle:    This is really good if you have, let's say, 2 political parties, and you want to present election results across several voting units, or similarly structured data.  However, I need to visually represents this: (5 political p...
I am currently implementing arrows in my force layout as is done in this example (http://bl.ocks.org/mbostock/1153292) and that works perfectly. However, one will quickly realize that the location and size of the arrows are hard-coded here since the...
I want to achieve something like this:   With the following attributes:   groups are rounded rects, which never overlap every node group has a horizontal centered title at the top, at least one node, and at least one link every node has a label a typ...
when using the force layout in d3.js it is possible to push nodes away with the help of the collision force by increasing an imaginary radius that surrounds the nodes.  I created a seperate button named button and i want to use .data() (to select a w...
I am using the Force Directed Graph to build a kind of flow diagram. It works fine except that the nodes have no specific order. They are random. I would like the graph to follow a hierarchical order.  var force = d3.layout.force()     .nodes(d3.valu...
