Is anybody working on a D-based really fast OpenGL-based 
visualization engine that supports tessellation of 2d primitives 
on the GPU?

For instance, if I want to animate a huge amount of circles (in a 
2d-graph) and I would like to only have to send an array of 
centers and radiuses and optionally colors, and transparencies to 
the GPU and then have the circles tessellated and rasterized 
there.

I need this for visualizing and animating huge graphs 
(potentially millions of nodes) using the powers present in 
modern day GPUs.

I'm interested in both pure-D implementations and wrappers over 
open-source C/C++ based implementations supported by Linux.

Does a Vulkan-based implementation in D provide any benefits with 
regards to CPU-to-GPU-data-transfer and on-GPU-tesselation?

I also need an engine to draw 2d (and 3d later) primitives like you've 
described above. I have a couple of unfinished attempts to make 
something like it. My specific is ability to inspect the data using some 
treeview widget. I considered GTK and Qt (both pure Qt and Qml) and they 
were too complex to make such user interface. The most suitable variant 
for me was dear imgui, but now I'm replacing it by nuklear. Generally I 
have no complete solution to the problem, but I'd like to join efforts 
to create it.

Is nuklear a software project that can be found somewhere?

Ahh, I presume you mean

I use dpp to make binding to nuklear, my second attempt

In general I'd like to make an utility that can read some files and draw 
their content. First of all I'm interested in time series visualization. 
Also it would be nice to have something like simple form of ParaView
