Yes, using Rollup you can make a smaller build. (See other comment where I linked to an example.) d3-axis depends on d3-selection and d3-transition, so it’ll be one of the last modules to be released, I expect. That said most of the functio

Ordinal scales don’t have a continuous input domain, so you can’t plug them into the zoom behavior like a linear scale. You could have the zoom behavior transform the scale’s output range instead (or equivalently, use the zoom behavior to a

The speed comes from doing less. :) Selections are designed so that you only modify the parts of the DOM that need to be updated, and don’t waste effort touching parts that are unchanged. The downside is that it can be more work for you, si

This is not a new ambition; it has been my goal since starting Protovis in 2009. It’s working out okay so far, but I totally agree that things can go off the rails if you spend too much time thinking about abstraction and not about practica

1. There’s room for improvement here. There’s some useful stuff in d3-array ( https://github.com/d3/d3-array ), particularly the nest and histogram operators. There’s also science.js ( https://github.com/j

Including dependencies and localization, d3-scale is 69KB minified and 24KB gzipped. You can make it smaller by excluding optional dependencies if they are not needed, such as d3-time and d3-time-format; you can make it even smaller by crea

I’m not sure; it would depend on what you want to “ask” your data / what you want to learn from the visualization. I would look for existing visualizations with similar applications for inspiration, and I would try a bunch of forms (wi

Two major differences. First, it represents the 4.0 API, so it’s a preview of what “vanilla D3” will look like sometime next year when D3 4.0 is released. Second, it’s a library you can use independently of the rest of D3. So if you don’t n

Most attempts to create cross-platform abstractions have been a failure because they (necessarily) oversimplify, and you are left with a common-denominator approach that lacks in expressiveness, performance, or both. It’s better to use the

I haven’t used React enough to form a strong opinion on right vs. wrong, but one of my objectives in decoupling D3 (see the new modules at https://github.com/d3 ) is to make it easier for people to use just the parts of D3 t

It’s expensive (in terms of effort) to design for multiple screens, but often necessary. Responsive design isn’t something that can be transparently solved by technology because it’s a design problem to decide what you want to show on diffe

Aren’t these textures already reusable? The constructed texture object (the result of textures.lines(), e.g.) can be called on as many selections as you like to reuse it. I feel it’s a matter of taste, but one practical reason I prefer chai

Agreed. It’s more of a what-if machine than an attempt to make the most accurate prediction. Incorporating Elo ratings into the simulator is actually easy: the difference between the two ratings tells you the probability of one team winning

It’s just an arbitrary number that’s hopefully large enough that everyone sees approximately the same result. It would be nice to calculate the exact variance of our estimate, though. (An earlier version continued simulating indefinitely bu

Toggles aren’t a great solution; it’s a pain for you since you need to opt-in, and it’s a pain for the designer since they now have to create two different versions of the site. I think either we figure out how to use scrolling effectively

If you follow rule 2 and adapt content to the viewport (rather than listening to wheel events directly), then middle-click scrolling should continue to work fine.
