I am trying a simple pie chart with labels inside the slices. I can display the labels but all not all. e.g. in the sample code I have Rick 5%, Paul 4% and Steve 3% are not displayed because of the small size of the slices. How can I overcome the problem?

This line of your code determines which slices get label text appended to them:
arcs.filter(function (d) {
return d.endAngle - d.startAngle > .2;
})
.append("svg:text")...
So slices where the total arc angle is less than 0.2 radians will be filtered out, and label text will not be added.
You could just reduce the filter value, to display the labels on thinner slices (e.g. change .2 in this example to .05) to get the effect you want:
your very small data is not being displayed because it is being filtered out by this code. if you remove this piece of code, then those small data will also be displayed.
arcs.filter(function (d) {
return d.endAngle - d.startAngle > .2;
})
However label will not be displayed clearly in small data. Displaying labels outside pie chart will display labels a bit clear.

I was trying to plot linechart with the linear scale for x-axis and log scale for y-axis, I was able to get ticks on x-axis and unable to get ticks on y-axis, approximate domain for y-axis for which I was trying to plot is (min:0.97, max:0.99).
For more information
I am sharing the code snippet for what I was trying to implement using d3js.

codepen snippet:- https://codepen.io/shanmuks/pen/ZEQBpYm
I'm trying to write an example using D3.js where images lay on a static background. I can move the background and zoom and I can also move separate images (something like this but with images). Also, I need to display a tooltip when the mouse is over an image.
Here what I have tried with d3js v4:
Problems:
When zooming the tooltip is displayed at an incorrect location (The problem is obviously in handleMouseOver where d.x,d.y is just the initial position of the image, but I don't know how to get translate and scale parameters of the current view)
Width of tip is not resized automatically to the text width (should I change div.tooltip somehow?).

Also, I have tried d3js v3 and the d3-tip library:
They work, but have some side effects:
For some reason, I can't move images separately.
When I zoom I want the tooltip to disappear (now it just stays at the same location and is even not redrawn at a new position and at the scale of the image)
Sometimes something like 'blinking' of the tooltip is happening (looks like it turns on and switch off many times when the cursor is near the edge of the image).

Update:
I figured out that adding d3.event.sourceEvent.stopPropagation(); were crucial, now I can move images separately. But the problem that looks like mouse cursor is moving faster than the image itself and also I subtracted half of image w,h (in my case 32/2) to drag the image at the center (by default it was the upper left corner).
function dragging_start(d) {
d3.event.sourceEvent.stopPropagation();
d3.select(this).raise().classed("active", true);
}
function dragging(d) {
d3.select(this).select("image")
.attr("x", d.x = d3.event.x-16)
.attr("y", d.y = d3.event.y-16);
}
i am unable to resize my bar chart within a script tag. Currently the bar chat is showing up massive on the page and I would like to resize the chart into a smaller size on the page.

Add a viewBox attribute to the svg element. This will allow you to lock the svg to the exact dimensions of your graph using the min-x, min-y, width and height parameters.
Then you can resize the svg element and you're graph will stretch to grow bigger or smaller.
https://www.w3.org/TR/SVG11/coords.html#ViewBoxAttribute
Edit:
Here is your js fiddle updated to use viewBox. I've commented out the width and height attributes so that it resizes as you make the page wider or narrower.

Is this the sort of thing you're looking for?
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)
})
})

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.
