How to offset text in D3 node - javascript

I am trying to use the D3 javascript library to make a force-directed graph, and I want to offset text appended to my nodes. However, no attributes that I seem to try and change have an affect on this. Instead, my text gets overlayed on the node and it's very hard to read:
Here is how I am appending the text:
node.append("text")
.attr("dy", -3)
.attr("text-anchor", "right")
.style("color", "white", null)
.text(function(d) { return d.name; });
I have tried different values of dx and dy but nothing seems to offset the text. It always looks the same.

You can translate the text element:
node.append("div")
.style("transform", "translate(0px,-10px)")
...
.html(...);
The name of the "transform" property depends on the browser you're using, see here. You might want to set all of these.


node.append("text")
.attr({
"dy": -3,
"transform": "translate(" + 15 + "," + 5 + ")"
})
.style("color", "white", null)
.text(function(d) { return d.name; });

D3 Map - Marks Zooming

I have a problem with marks on my D3 map. When I set up zooming for each state the marks are not zooming within the map..
That's my first try for D3 map, so sorry if I messed up something in the code. If I did or missed something I'll really appreciate explanation.
If anyone can help with that I'll be really thankful.

The problem is that you are appending your circles to the svg directly, but your US state are being appended to a g element. Your zoom transition is only applied to the g, meaning the circles will be unaffected:
g.transition()
.duration(750)
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")scale(" + k + ")translate(" + -x + "," + -y + ")")
.style("stroke-width", 1.5 / k + "px");
You should be able to correct this by simply appending your circles to the same g element itself, rather than the svg:
d3.json("cities.json", function(data) {
g.selectAll("circle")
.data(data)
.enter()

Unable to display the tooltip and arctween transition ata a time in d3 pie chart

Thank you SiddP for suggesting some useful tips. Based on his codes and my research I have added a legend along with arctween and tooltip to this pie chart to make it complete. I hope this helps someone struggling over D3 pie chart.
Thank you stackoverflow. :}

I am trying to make a pie chart with the provided dataset and I am facing error. How to define the parameter d to fetch the data from the variable "data" and its subsequent values "IP" and "count"? I dont know what mistake I am doing in my codes. What should I change in my current codes so that I can get a pie chart with current data format? Please help me. I am stuck. The condition is I should not use any kind of .csv or .tsv file in this code for importing. Thanks for any help.

One issue is with your data array... you need to remove the first item in it [ Also, you are missing a ',' after the item. but the item is itself not required as its an array ].
Second is with d.data.count inside the pie function... you need to refer it as d[1] as you need to plot the second item in data array in your chart.

Your data input format is wrong.
Change from:
var data = [ ["IP", "count"]
["192.168.12.1", "20"],
["76.09.45.34", "40"],
["34.91.23.76", "80"],

["192.168.10.89", "50"],
["192.178.34.07", "18"],
["192.168.12.98", "30"]];
to
var data = [
{"IP":"192.168.12.1", "count":"20"},
{"IP":"76.09.45.34", "count":"40"},
{"IP":"34.91.23.76", "count":"80"},

I need to draw a chord in d3 in eclipse shape rather as circle

Here is my sample js file i need to draw a chord but in eclipse shape rather then a circle. Secondly i need to know that what is a matrix use while creating chord diagram and are we able to draw a chord with simple json file (without using matrix) as mentioned http://www.delimited.io/blog/2013/12/8/chord-diagrams-in-d3 here.
