How would you implement this with d3.js:
I started with sunburst diagram, but how to handle pics around circle? How to rotate them? etc. (assume each cheese has its png pic)
To add images, you can use the SVG image tag. The elements added in this way can be translated and rotated in the usual manner. The code you're going to need is essentially the same as for a pie chart with rotated labels, for which you should be able to find plenty of examples.
Here's a quick and dirty modified pie chart example that demonstrates the technique.

Here I am trying to draw a gauge graph according to the following design. So far I have found a couple of examples from codepen on drawing gauge graph
But I was not able to find any documentation for styling these graphs.
I'm looking for a way to achieve those inner shadow overlays inside the circle on hover.
I really appreciate your help on this - I'm fairly new to D3.
I am working on a sort of nested D3 viz. When one element in the first D3 viz is moused over, I want a second D3 viz (say bar chart distribution of the first's elements) to appear. Is this possible? Could you give me a high level overview of how to implement?
To further illustrate: Let's say first viz is scatter plot of GDP vs. population of various countries. When a particular country on the scatter plot is moused over, I want a bar chart to appear in the tooltip that shows the top 5 industries in that country.
Any help on how to approach this would be much appreciate. Thank you again!
I suggest you to take a look into Bootstrap's "popover". I like it because is very easy to use. Inside that popover you can insert SVG element and draw your second visualization.
To keep things clean and reusable, I suggest you to read this article and write your second chart in reusable manner.
I am using the Zoomable Pack Layout provided on the D3 website: http://mbostock.github.io/d3/talk/20111116/pack-hierarchy.html
All labels of the circles are displayed when the layout is displayed.
The problem is that for small circles which are close together, the labels overlap. I would like to know if there is a way to hide the overlapping text of the labels?
I have read about "foreignobject", but if this is the answer, I am not sure how and where to incorporate it in the code.
You could restrict the display of text based on either the level of the hierarchy, the radius of the circle or a combination of both. Both are in the pack output. Use titles for hover detail.
Does anyone know of good examples producing a polar plot using the D3 Javascript libraries?
I've seen some rose plots like this and this, but I'm really looking for something more similar to the Matlab polar plot:
Any examples would be greatly appreciated. Thanks!
Sure, here you go:
The function is plotted using d3.svg.line.radial. The background radial grid is implemented as line, circle and text elements. One minor annoyance is that the code needs both radians (for d3.svg.line.radial) and degrees (for SVG’s transform attribute). I used rotated text labels because that was easy to do with SVG, but you could use non-rotated labels if you don’t mind a little trigonometry to position the text labels.
Note carefully the definition of the line’s angle: D3’s radial lines and areas proceed clockwise starting at 12 o’clock, while this plot proceeds counterclockwise starting at 3 o’clock!
Plotly lets you make interactive polar charts with MATLAB, Python, and R. The results are interactive, and rendered with D3.js. You can see a few MATLAB examples (code + interactive graphs) here.

I'm looking for a charting library that can draw heatmap charts, and has the option of displaying column label text vertically (allowing me to fit lots of columns on the screen regardless of the length of the labels)
Ideally the library would be free for a charity/educational organisation.
Here's an example of a simple heatmap with vertical labels:
That chart was created using FusionCharts, which is not suitable as it is a flash-based product and is expensive to license.
You could always roll this yourself. Most of the table can be generated using ordinary HTML, with the exception of the vertical labels at the bottom. You could tackle that with Rafael, a JavaScript library that allows you to draw on an HTML canvas. Drawing rotated text is actually available out of the box so it won't be hard to implement.
I think what you are looking for is also called a TreeMap (in some circles anyway).
Check out thejit.org
Under the demos checkout the treemap and the icicle chart.
