javascript - D3.js network graph using force-directed layout and rectangles for nodes -

-

i'm trying modify mike's force-directed graph example use rectangles instead of circles nodes. also, want text inside rectangle.

i have rectangles showing text correctly, they're not attached links, , not move.

here's codepen link: http://codepen.io/anon/pen/gpgwaz

var width = 960,     height = 500;  var color = d3.scale.category20();  var force = d3.layout.force()     .charge(-120)     .linkdistance(30)     .size([width, height]);  var svg = d3.select("body").append("svg")     .attr("width", width)     .attr("height", height);  force     .nodes(graph.nodes)     .links(graph.links)     .start();  var link = svg.selectall(".link")     .data(graph.links)     .enter().append("line")     .attr("class", "link")     .style("stroke-width", function(d) {         return math.sqrt(d.value);     });  var node = svg.selectall(".node")     .data(graph.nodes)     .enter()     .append("g")     .attr("transform", function(d) {         return "translate(" + d.x + "," + d.y + ")";     })     .call(force.drag);  node.append("rect")     .attr("class", "node")     .attr("width", 100)     .attr("height", 35)     .style("fill", function(d) {         return color(d.group);     })     .style("stroke", "black")     .style("stroke-width", "1px");  node.append("text")     .text(function(d) {         return d.name;     })     .style("font-size", "12px")     .attr("dy", "1em");  node.append("title")     .text(function(d) {         return d.name;     });  force.on("tick", function() {     link.attr("x1", function(d) {             return d.source.x;         })         .attr("y1", function(d) {             return d.source.y;         })         .attr("x2", function(d) {             return d.target.x;         })         .attr("y2", function(d) {             return d.target.y;         });      node.attr("x", function(d) {             return d.x;         })         .attr("y", function(d) {             return d.y;         }); });

update

thanks lars's comment, , codepen works now.

updates made code:

  1. add transform illustrated lars
  2. changed links connect @ center of rectangles
  3. added rounded corners rectangles
  4. gave text slight margin indentation
  5. changed use window width/height

here new codepen: http://codepen.io/anon/pen/bdgred

var width = window.innerwidth,     height = window.innerheight,     nodewidth = 100,     nodeheight = 35;  var color = d3.scale.category20();  var force = d3.layout.force()     .charge(-1500)     .linkdistance(100)     .friction(0.5)     .size([width, height]);  var svg = d3.select("body").append("svg")     .attr("width", width)     .attr("height", height);  force     .nodes(graph.nodes)     .links(graph.links)     .start();  var link = svg.selectall(".link")     .data(graph.links)     .enter().append("line")     .attr("class", "link")     .style("stroke-width", function(d) {         return math.sqrt(d.value);     });  var node = svg.selectall(".node")     .data(graph.nodes)     .enter()     .append("g")     .attr("transform", function(d) {         return "translate(" + d.x + "," + d.y + ")";     })     .call(force.drag);  node.append("rect")     .attr("class", "node")     .attr("width", nodewidth)     .attr("height", nodeheight)     .attr("rx", 5)     .attr("ry", 5)     .style("fill", function(d) {         return color(d.group);     })     .style("stroke", "black")     .style("stroke-width", "1px");  node.append("text")     .attr("x", 5)     .attr("y", 2)     .text(function(d) {         return d.name;     })     .style("font-size", "12px")     .attr("dy", "1em");  node.append("title")     .text(function(d) {         return d.name;     });  force.on("tick", function() {     link.attr("x1", function(d) {             return d.source.x + (nodewidth / 2);         })         .attr("y1", function(d) {             return d.source.y + (nodeheight / 2);         })         .attr("x2", function(d) {             return d.target.x + (nodewidth / 2);         })         .attr("y2", function(d) {             return d.target.y + (nodeheight / 2);         });      node.attr("transform", function(d) {             return "translate(" + d.x + "," + d.y + ")";         }); });

you're setting x , y attributes on g elements change positions -- won't anything. need set transform attribute instead, you're doing when adding g elements. tick handler function contain

node.attr("transform", function(d) {     return "translate(" + d.x + "," + d.y + ")"; });

instead of

node.attr("x", function(d) {         return d.x;     })     .attr("y", function(d) {         return d.y;     });
