I have tried searching for an answer to this problem but have not been able to find anything that defines my problem.
I have created an Interactive Tree Diagram Menu for my Sharepoint site using D3.js and HTML (Code Below)
In Codepen it works fine and I can adjust the width and length of the SVG using the width and length variables:
// Set the dimensions and margins of the diagram
var margin = {top: 20, right: 90, bottom: 30, left: 90},
width = 960 - margin.left - margin.right,
height = 300 - margin.top - margin.bottom;
But no matter what I seem to enter in as the height, once I open this up in a browser the SVG is at least 500px high and taking up way too much empty space.
when I publish this on my Sharepoint site via an iframe, the white space can be even bigger.
I have tried setting the iframe width and height dimensions to 500px, 300px, 100% 50% etc. but it doesn't solve the problem, all it does is mean that you have to scroll within the iframe.
I think it may have something to do with the transform/translate settings in the d3 code but I just can't figure it out - any help would be greatly appreciated!

******** BONUS Question **********
Anyone who can tell me to set it up so that three levels of the collapsible tree diagram are shown by default instead of 2 will be awarded 10 internet points!
Have you tried setting the svg width and height attributes to 100%,
and then set the width/height of the containing div (not the iframe)?
This seems to provide consistent results for me. For example, I
changed your JS to: var svg =
d3.select("#Menu").append("svg").attr("width", "100%").attr("height",
"100%").append("g").attr("transform", "translate("+ margin.left + ","
+ margin.top + ")"); and added #Menu { width: 960px; height: 300px; } to your styles. – odin243 Dec 21 at 21:25
This worked a treat
I have created a horizontal tree diagram as shown in below image. I want straight lines between nodes. The curved lines between nodes are default in d3 js. I saw some answers on google for this but did not found any satisfactory result. So is it possible to draw straight lines between nodes in d3 js? If yes then how can I do that?

Define your line :
var line = d3.svg.line()
.x(function(d) {
return d.y; // because tree is horizontal
})
.y(function(d) {
return d.x; // because tree is horizontal
});
Change your links function to this because d3.svg.line() takes array of points as argument
Hope this helps
// Enter the links.
link.enter().insert("path", "g")
.attr("class", "link")
.attr("d", function(d) {
return line([d.source, d.target]);

I am getting json data from backend. using the back-end data, I am trying to draw a line chart.
But the chart is very ugly, since the number values are not converting properlty. also i am not getting x axis values as date values here. how to convert the date number to properly here?
my try :

I think you really want to remove links that have cardinalita === "0" and have no children:
// Transition links to their new position.
link.transition()
.duration(duration)
.attr("d", function(d){
if (!d.target.children && d.target.cardinalita === "0")
return "M0,0"; //<-- draw nothing
else
return diagonal(d);
});

I have a d3 focus/context chart where I would like to be able to pan on the focus portion after brushing the context, and I would like the brushed section of the context area to move in sync with the panning of the focus area. However, when I click on the focus portion after I select a region in the context chart, the focus scale changes and the points no longer show up at the correct coordinates. The following code is available on jsfiddle as well:

To reset the brushing after panning, you would need to reset and call brush.extent again:
//Find extent of zoomed area, for example the edges of graphed region
var brushExtent = [x.invert(0), x.invert(width)];
context.select(".brush").call(brush.extent(brushExtent));
Here's an example of focus/context brushing panning synchronization on a line graph:

Hope that helps!
