I found a [web page](https://bost.ocks.org/mike/algorithms/) with a lot of dazzling and interesting javascript visualization examples. It’s true that programming language is the best drawing tool. Since Julia is very fast and easy to use, I assume it can do a lot of visualization work, and even some are difficult to do in other languages. So, are there any interesting visualization examples in Julia about chaos, fractal, CV, NLP, optimization… or anything else?

Welcome to the community @Wind  
I think there are some examples created with Plots.jl but I don’t have links for them but some others might. Just saw some on Twitter tagged with #julialang and maybe animation. Another variant is to use Makie.jl for it which supports 3D stuff.

@TheCedarPrince and I wanted to see more of that kind of animations though and created a library for it. It’s definitely not there yet but you mind find it interesting.  
The library: [GitHub - JuliaAnimators/Javis.jl: Julia Animations and Visualizations](https://github.com/Wikunia/Javis.jl)

Some animations:

Well, turns out Fourier was not just a great mathematician but also an artist so his first attempt was a success: I guess I should also mention this was done entirely in Julia. After a bit of pre-processing on the julia logo, the drawing itself was done all with [Javis.jl](https://github.com/Wikunia/Javis.jl) (kudos to @Wikunia and @TheCedarPrince for the amazing package, very e…

I have a package named [**WordCloud.jl**](https://github.com/guo-yong-zhi/WordCloud.jl). Word clouds are used to visualize text data, and **WordCloud.jl** is the most flexible one as far as I can see. It can generate some results that other generators can’t. This is because the non-greedy bin packing algorithm it uses is **flexible** but very **time-consuming**. I’ve taken a lot of optimizations (quadtree, parallelism, generations, LRU, and so on) to ensure it runs fast enough. But I can’t imagine how to implement it without a great language that as **usable** as Python and as **fast** as C 😏.  
Here are some examples.

WordCloud is really an interesting stuff. The text data is clear at a glance. BTW, the comparison GIF is impressive.

Can we rank the most said words? like how many `America` word has been said.

Do you mean rank words in a specific document? If my understanding is correct, it can be easily done by something like that

```julia
using WordCloud
doc = pkgdir(WordCloud) * "/res/alice.txt"
sort(collect(countwords(open(doc))), by=last, rev=true)

```

> 3019-element Vector{Pair{String, Int64}}:  
> “the” =\> 1530  
> “and” =\> 803  
> “to” =\> 725  
> “it” =\> 523  
> “she” =\> 506  
> “of” =\> 503  
> “said” =\> 456  
> “Alice” =\> 398  
> “in” =\> 359  
> ⋮

It’s not so much like a common optimization problem, which has a continuous and differentiable optimization objective function. For a nesting problem(or packing problem), the objective function can be `density` (minimize the waste of material). But for word cloud, high density is not the only target. It just try to get a well distributed (evenly scattered) layout on a set density. The uniformity is achieved by initialization. The only constraint of optimization is that words should not overlap each other. So, if there is any overlap, the value of the objective function is infinite, otherwise it is 0.  
The package [Stuffing.jl](https://github.com/guo-yong-zhi/Stuffing.jl) provides optimization algorithm for WordCloud.jl. The introduction of the algorithm can be found [here](https://github.com/guo-yong-zhi/Stuffing.jl#algorithm-description).

Aha, so something like

```nohighlight
   maximize Base font size
 subject to Everything fits in the frame
              No words overlap each other

```

?

Very cool project, I might try copying the algorithm one day as an exercise…

The `Base font size` is calculated according to the set density in advance and remains unchanged throughout the optimization process.

This package of yours can be great, imagine if we can use sensor that read people mind and know what they think mostly everyday, in a week, in a month, in a year. Then gather all people in a planet…
