Hey,

I am trying to find a pretty logo for Copulas.jl and would like some help to find a good idea & to realize it correctly. Two years ago i had an idea in [this thread](https://discourse.julialang.org/t/how-may-i-reproduce-the-distributions-jl-logo/76631) to simply apply the rank transformation to (a bad reproduction of) the Distributions.jl logo as follows:

 ![first_attemps](https://global.discourse-cdn.com/julialang/original/3X/7/7/77750b8915458d7f48e7d43f3c14cff6a0d47627.png)

But this looks a bit messy (and I am not sure the colors are right). Thoughts & Comments ? Maybe some other reprensentation would be more efficient to convey what this logo should ?

Maybe copy off of the Distributions.jl logo but use countour plots using 3 different copulas instead of simple scatter plots like they did?

Could not find out how to plot contours ^^

Another version that simply changes marginals but keep the dependence structure of the Distributions.jl’s logo:

Looks a bit like a plane 🤣 or a bat. Definitively something flying.

With a discrete marginal:

Logos have to look nice when are small. I would go for some interpretation of those, drawn in simple shapes. Like:

![image](https://global.discourse-cdn.com/julialang/original/3X/1/a/1a46207654e55f6fbd4598d2670a11a5e5c96867.png)

(I like drawing logs, rs, but I’m not suggesting actually these, as I don’t know what exactly could be representative of what the package does)

@lmiq I see your point and you are probably right.

Those two are nice btw. Could you make the first one with a slightly different shape, matching e.g. this one:

 ![image](https://global.discourse-cdn.com/julialang/original/3X/7/f/7f3b05a6c8bb28ae912fd6427ccab5fe71637b61.jpeg)

but with a bit less lines and the same kind of coloring that you did on the first one. SO basically the first one you had but it bit more “pointy” on the right hand side.

A better version, but scatterplot.

 ![v6](https://global.discourse-cdn.com/julialang/original/3X/0/8/088f6a010f938df91394fb43b2bfb85c4c0636b3.png)

The hotspot is on the top right, while the bottiom-left has another less-hot spot. The shape is symetric w.r.t. the y=x line

Nice, but looks a bit… phallic 😕 Maybe the purple/blue frontier cvould be more parralel to the purple/white one ?

Rs… You know that in latin languages “copula” does not sound very well either…

Yes I do ! It actually has a nice interpretation: a copula makes a “tuple” from univaraite distributions (not restricted to d=2 for a “couple” though, which has the same latin root as copula)

I have to leave now, but we can improve on this later, if you want.

I’ll try to sketch something with pen & paper so that we get a better idea next time then.

Sadly I do not have the skills to do that, but thanks a lot 🙂

A quick hand sketch.

 ![IMG_20240118_201555 (002)](https://global.discourse-cdn.com/julialang/original/3X/7/6/76fd13dc6ce8357d41b9d6b26270ea58cf2d14ef.jpeg)

Basically (1) and (2) are drawing lines to give the “direction”, and then (3) tries to reproduce the contour plot idea. Discard (4), i actually prefer (3).

If we remove the drawing lines, and keep the black square around and the julia-colored regions I think this can be quite OK.

The top-right region has to be “squeezed out” : at the limit every region should be touching the corner, at least theoretically.

On your drawing, I would reduce the thickness of the lines separating the regions.

Any chance of getting a formula for those curves?

Have you looked at [Github’s copulas logo?](https://github.com/topics/copulas)

On that same spirit:

This one is pretty indeed but the grid of linked circles looks like a mark of the organisation behind this python package and has nothing to do with copulas themselves afaict. However I like the text on the bottom maybe I should keep that in mind.

Yes, I have no idea how it relates to copulas, but the authors, also being experts on the subject, should know. They use the logo everywhere - see a better example [on the left banner of their tutorials.](https://sdv.dev/Copulas/).
