I am new to d3 and javascript in general. I build this fiddle here, which is a basic d3 force diagram, with an .onmousover event which shows a div tooltip when the user hovers over a node
https://jsfiddle.net/1qe1gp06/20/
the content from the tooltip comes from the node data
var nodes = [
{ x: width/3, y: height/2, "content":"small" },
{ x: 2*width/3, y: height/2, "content":"biggerbiggerbiggerbiggerbiggerbigger"}
];
d3 node javascript
var node = svg.selectAll('.node')
.data(nodes)
.enter().append('circle')
.attr('class', 'node')
.on("mouseover", function(d) {
div.transition()
.duration(200)
.style("opacity", .9);
div.html(d.content + "<br/>" + d.content + "<br/>" + d.content + "<br/>" + d.content + "<br/>" )
.style("left", (d3.event.pageX) + "px")
.style("top", (d3.event.pageY - 28) + "px");
})
.on("mouseout", function(d) {
div.transition()
.duration(500)
.style("opacity", 0);
})
;
append div tooltip
var div = d3.select("body").append("div")
.attr("class", "tooltip")
.style("opacity", 0);
css for the div tooltip
div.tooltip {
position: absolute;
overflow: hidden;
text-align: center;
width: 200px;
height: 50px;
padding: 2px;
font: 15px "Courier New";
color: #F2F3F4;
background: #5D6D7E;
border: 1px;
border-radius: 5px;
border-style: solid;
border-color: #BDC3C7;
pointer-events: none;
}
However, I don't know how to scale the tooltip so that it expands or shrinks based upon the length of the text or number of line breaks in the content.
enter image description here
It is probably easiest seen in the fiddle
can anyone help please?
thanks
I have forked and updated your fiddle I had to make a few corrections so it would run (probably just some typos and not relevant to the question). The thing that needed changing was:
div.tooltip {
width: 200px;
}
to
div.tooltip {
width: max-content;
}
Hard coding a width will enforce that width regardless of the elements contents. max-content will basically make the div as big as it needs to be to fit what is inside. MDN Docs
I have a map created using D3 and JavaScript. I want to translate the names of Spain's provinces to another language, for example, to English. By default it is Spanish.
I would prefer to make these changes manually, however, I don't know which file should I edit. I tried to edit hdi.json and provincias.json, but it does not work (I get the provinces colored in black without any title, like it is not recognized).
Any help is highly appreciated.

It seems that you're using this JSON for the provinces in Spain.
If that's correct, the file is "provincias.json" and this is the path for the names:
provincias.objects.provincias.geometries[index].properties.nombre
Where index is the index you want in the geometries array.
Check this demo:
d3.json("https://cdn.rawgit.com/rveciana/5919944/raw//provincias.json", function(provincias) {
provincias.objects.provincias.geometries.forEach(function(d) {
console.log(d.properties.nombre)
})
})

I'm trying to draw svg map with d3 from topojson file, but all I got is messed up lines.
I'm using most of the code I found on http://www.tnoda.com/blog/2013-12-07. When I use topojson files from that site, everything works fine. I tought maybe the problem is in my topojson file, but when I import it in mapshaper, I get normal map.

I was having the exact same problem and spent hours re-converting my SHP file to GeoJSON/Topojson in command line with different settings. The solution is quite simple!
- Get QGIS here: https://www.qgis.org/en/site/forusers/download.html
- open your SHP file or GeoJSON file
- Select the layer you want to export
- Go to Layer > Save as
- Format: Geojson
- CSR: WGS 84, EPSG: 4326
- Save.
Enjoy!
Hello I have a D3 script that outputs a bunch of donut charts and I am looking for a way to filter and search out keywords in the name of the first columns of my data. I would like to be able to do this live and am not looking for a way to filter the data specifically just but a search bar or some other way to allow users to search and filter through the donut charts. My biggest problem is incorporating the search element into the d3.csv() part I understand how to make a searchbar and have incorporated an example of one that I would like to be able to search through my data. I have done more research and perhaps using jquery would help.
Here is my D3:

I have seen examples of how to filter by set values but would like to have a search bar. Keep in mind I am relatively new to D3 and JS.
I am embarking on a journey to learn to visualize data using d3.js, and so far I am finding the "Interactive Data Visualization" by Scott Murray very helpful. I was following through some of the example codes in book chapter 11, and was wondering how I would add the tooltip to the pie chart (the book already describes this procedure using the bar chart). Anyways, just been tinkering around with the codes for past couple of hours and would like to see if anyone can lend me a hand on this:

I know this is bit to digest, but what I want to know more specifically is how to set the x and y value for the tool-tip. Thank you in advance.
I prefer to use the opacity to show/hide the tooltip. Here is the FIDDLE. This should get you going.
d3.select("#tooltip")
.style("left", d3.event.pageX + "px")
.style("top", d3.event.pageY + "px")
.style("opacity", 1)
.select("#value")
.text(d.value);
I'm adding mouse move event on FernOfTheAndes's answer, This will makes it more pretty usecase. Hope this will be helpful
.on("mouseover", function(d) {
d3.select("#tooltip").style('opacity', 1)
.select("#value").text(d.value);
})
.on("mousemove", function(d) {
d3.select("#tooltip").style("top", (d3.event.pageY - 10) + "px")
.style("left", (d3.event.pageX + 10) + "px");
})
.on("mouseout", function() {
d3.select("#tooltip").style('opacity', 0);
});
