I don't understand how to display text on my nodes
I tried several times but didn't work, please help me to solve it
I'm not familiar with D3.js at all but I need to visualize a graph for my project, and I need this additional feature (display label) on the nodes
Here is the input file:
{
"nodes":[
{"name":"A","group":0},
{"name":"B","group":1},
{"name":"C","group":2},
{"name":"D","group":3},
{"name":"E","group":4}
],
"links":[
{"source":0,"target":1,"value":11},
{"source":0,"target":2,"value":11},
{"source":1,"target":2,"value":21},
{"source":1,"target":3,"value":21},
{"source":1,"target":4,"value":21},
{"source":2,"target":3,"value":21},
{"source":2,"target":4,"value":21},
{"source":3,"target":4,"value":11}
]
}
D3.js Code:
<script type="text/javascript">
// use print_graph() method to output graph vertices
main_graph();
var width = 700,
height = 300;
var color = d3.scale.category20();
var force = d3.layout.force()
.charge(-120)
.linkDistance(150)
.size([width, height]);
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.attr("transform", "translate(0,0)");
d3.json("input.json", function(error, graph) {
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("circle")
.attr("class", "node")
// size of nodes
.attr("r", 20)
.style("fill", function(d) {
return color(d.group);
})
.call(force.drag);
//I'm stuck here
var texts = svg.selectAll("text.label")
.data(graph.nodes)
.enter().append("text")
.attr("class", "label")
.attr("fill", "white")
.text(function(d) {
return d.name;
});
/*
// 1st trying
var text = svg.selectAll("text")
.data(graph.node)
.enter().append("text")
.attr("fill","white")
.text(function (d) {return d.name; });
*/
// another trying
//node.append("text")
//.text(function(d) { return d.name; });
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("cx", function(d) {
return d.x;
})
.attr("cy", function(d) {
return d.y;
});
});
});
</script>
How you are adding the text is fine but in your force.on("tick", function() {}) handler you don't position the them:
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("cx", function(d) {
return d.x;
})
.attr("cy", function(d) {
return d.y;
});
texts.attr("x", function(d) { //<-- NEED TO POSITION THESE TOO
return d.x;
})
.attr("y", function(d) {
return d.y;
});
});
Here's your code fixed.

I am trying to wrap text which is parsed from a json response into my application.
I have two svg elements : rect and text. I want to find a way where I can wrap my svg text such that it fits in the rectangle.
( Picture Force layout with text labels and rectangles )

I'm able to get images and labels to show for the nodes, but they show at the top left of the screen.
Nodes show up in the correct position when I use this
.enter().append("circle")
Labels and node images show at the top left (incorrect) when I use this:
.enter().append("g")
This works with append "circle" (commented out in the code below):
When I comment out append circle and use append "g" (in order to use node images and labels) the images and labels all show up near (0,0) instead of near the node:
Also, what exactly is append "g"? Where is the documentation to find out what's possible with append "g"?
Here is all the code:

With .append("g") you insert a SVG Group Element.
The problem is, that you try to apply attributes that are for circles, like the radius with .attr("r",15), to the group element.
You have to use circles if you want to draw a circle. Group elements do not have any shape. They are used to group elements like circles.
A solution would be to append the g element and transform it to the location of the node. I updated your code in the following snippet. I used the group elements and added the circle, image and text inside the group elements.
Moreover I removed the backslashes before each angular bracket and set the title to the field name instead of label.

height = 500;

I will try to make a resume of my problem and give some additional information if someone have a lead for me.
I want to display the history of an element in an application. How it have been construct and what it have done. So it could have 1+ parents, 1+ brothers and 1+ children. It's like a genealogy tree but it could have 3 parents and parents and children can be mixed to give others children. So I thought about a network, and I ended with this :
http://jsfiddle.net/ggrwc8p6/3/
var data = {
"nodes":[
{"name":"1-STS","group":1},
{"name":"2-STS","group":1},
{"name":"1-ADN","group":2},

]
};
var width = 500,
height = 500;
var color = d3.scale.category20();
var force = d3.layout.force()

node.attr("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });
});
}
makeIt("",data);
My problem here are :
How can I make this like a tree ? From top to bottom and not with no hierarchy like here ?
How can I put some text in dot (title) and lines ?
Thank for the people that will help me.

I've been trying to glue ideas from various d3 examples into what i need, starting with the basic example using miserable.json data and then adding:
use of a key function for the data joins
modifying the underlying graph ala this example
making the links' linkDistance() function depend on an attribute of the graph's links'
adding labels to the nodes ala this example
So far i'm only 3 out of 4: something about using the g elements -- using code taken directly from the Mike's "Labeled Force Layout" example -- breaks things and the nodes aren't drawn. I can make it work if i join circle elements directly, but not if I interpose g elements with attached circles and text elements.
The code below is my best effort at a minimal example. This example works, but does not if I replace the .enter().append("circle") line with the .enter().append("g") lines.
Does anyone know why?

In your code you are setting cx and cy attributes to the g element. g elements does not support any position attributes like x, y or cx, cy. To move the contents of a g element you will have to use the transform attribute.
Your code
var node = svg.selectAll(".node")
.data(graph.nodes, function(d) {return d.idx; })
.enter().append("g")
.attr("class", "node")
.attr("cx", function(d) { return d.x; }) //will not work
.attr("cy", function(d) { return d.y; }); //will not work
Solution
var node = svg.selectAll(".node")
.data(graph.nodes, function(d) {return d.idx; })
.enter().append("g")
.attr("class", "node");
node.append("circle")
.attr("r", 10)
.style("fill", function(d) { return color(0); });
node.append("text")
.attr("dx", 12)
.attr("dy", ".35em")
.text(function(d) { return d.name });
Use translate function as below to move group elements.
function tick() {
//Moving <g> elements using transform attribute
node.attr("transform", function(d) { return "translate(" + d.x + "," + d.y + ")"; });
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; });

I still not understanding why the code bellow does not display its labels / text...
I have defined the css and set the attribute like the title when the move is over the node:
Json:
{
"nodes":[
{"name":"t1","group":1},
{"name":"t2","group":1},
{"name":"t3","group":1},
{"name":"t4","group":1},
{"name":"hate","group":2},
{"name":"good","group":2},
{"name":"aiport","group":3},
{"name":"flight","group":3}
],
"links":[
{"source":0,"target":4,"value":4},
{"source":0,"target":5,"value":4},
{"source":1,"target":4,"value":4},
{"source":2,"target":5,"value":4},
{"source":3,"target":5,"value":4},
{"source":4,"target":6,"value":4},
{"source":5,"target":6,"value":4},
{"source":5,"target":7,"value":4}
]
}
Code:
<!DOCTYPE html>
<meta charset="utf-8">
<style>
.node {
fill: #555;
stroke: #999;
stroke-width: 1.5px;
}
.link {
stroke: #999;
stroke-opacity: .6;
}
</style>
<body>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
var width = 1024,
height = 768;
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);
d3.json("data.json", function(error, graph) {
force
.nodes(graph.nodes)
.links(graph.links)
.start();
var link = svg.selectAll("line.link")
.data(graph.links)
.enter().append("line")
.attr("class", "link")
.style("stroke-width", function(d) { return Math.sqrt(d.value); });
var node = svg.selectAll("circle.node")
.data(graph.nodes)
.enter().append("circle")
.attr("class", "node")
.attr("r", 5)
.style("fill", function(d) { return color(d.group); })
.call(force.drag);
node.append("title")
.text(function(d) { return d.name; });
node.append("text")
.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("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });
});
});
</script>
</body>
</html>
You are adding the text element inside the circle element - try running your code and have a look at the svg with the DOM inspector. I'm not sure text is allowed there. Instead add the text elements separately - like another rendering of the nodes:
var texts = svg.selectAll("text.label")
.data(graph.nodes)
.enter().append("text")
.attr("class", "label")
.attr("fill", "black")
.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("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });
texts.attr("transform", function(d) {
return "translate(" + d.x + "," + d.y + ")";
});
});
Another option would be to add both circle and text elements inside a g container element as shown below:
var container = svg.selectAll("g.node").data(graph.nodes).enter().append("g")
.attr("class", "node")
.attr("transform", function (d) {
return "translate(" + d.x + "," + d.y + ")";
}).call(force.drag);
container.append("circle")
.attr("r", 5)
.style("fill", color);
container.append("text")
.style("text-anchor", "middle")
.text(function (d) {
return d.name;
});
