Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Help making plot for experiment
If you want a C++ solution you can use a library like matplot++.
-
Widely-used graphics library
If you want a strict C++ equivalent to SDL the clear answer is SFML. If you just want to visualize 2D/3D data there's matplot++. If you want something slightly higher-level than SDL/SFML (with pre-made UI widgets and such) there's imGUI. If you need an all-in-one GUI solution for desktop or mobile apps there's Qt.

Embedding matplotlibcpp plot into QT QWidget
If not, then ditch Python and matplotlib and use a different C++ native plotting framework such as matplot++

Best Library to Visualize Mathematical Concepts
The best way to visualize most mathematical concepts is by plotting a 2D graph. To do that you can use e.g. Matplot++

How to implement Matplotlib in C++
If you just want to plot graphs in C++ check out https://alandefreitas.github.io/matplotplusplus/. There is extensive documentation on how to use it. But if you haven't used a library before you should start here:
-
2D Animation for algorithms
Using a 3rd party UI library, you certainly can. E.g. with MatPlot++
- I want to make a program that draws a graphical function to a png and I don't know how.

C++ plotting library for Windows + MinGW similar to matplotlib in Python?
Maybe Matplot++ is the solution. You can check more info in https://github.com/alandefreitas/matplotplusplus

Brplot – plotting app/lib in C
Thanks for the post. The obvious comparison is feedgnuplot: https://github.com/dkogan/feedgnuplot/
That works similarly in that it plots standard input. The backend is gnuplot, which is a double-edged sword: it's far more full-featured than brplot, but almost certainly is much slower also. I'll try out brplot to see if it would be a good replacement for cases where speed is important. Thanks!

A command line tool that draw plots on the terminal
Oh hey Dima.
Feedgnuplot is really slick.

It's in the debian repos too.

D2: A new declarative language to turn text into diagrams
Is there a declarative language or framework to create ad-hoc GUIs that consume structured data from stdin stream and spit-out a GUI?
Like feedgnuplot [1] but not only restricted to graphs.

jupyter and vim
I found using shell as an interactive environment to be pretty productive using https://github.com/dkogan/feedgnuplot and https://github.com/dkogan/vnlog. The filesystem becomes your state (instead of in memory state of your Python interpreter) which forces you to write Unix-style tools. Plotting with feedgnuplot spins up an interactive Qt plotter which I often used to explore 3D plots. It's not "inline" and fancy and does take a bit of grokking but I eventually found it more productive than Jupyter, especially as my development moved away from Python.

termplotlib: Plots in the terminal
One of the tools I absolutely love is feedgnuplot which presents a stdin CLI interface to gnuplot.
-
Anyone know of a good Data Visualization Library?
Also, if one doesn't want to learn Gnuplot's DSL try using feedgnuplot which presents a stdin interface for whitespace delimited tabular data.
- Show HN: Simple tool for creating commandline bar charts
- Git 2.33 released with new “merge-ort” merging with 500~9000x speed-up

Best scientific graphing library?
Write space delimited tabular data (ideally in vnlog format) and plot it using feedgnuplot. Also helps decouple concerns (data generating application focuses on generating data).
What are some alternatives?
matplotlib - C++ wrappers around python's matplotlib
implot - Immediate Mode Plotting
matplotlib-cpp - Extremely simple yet powerful header-only C++ plotting library built on the popular matplotlib
ttyplot - a realtime plotting utility for terminal/console with data input from stdin
manim - Animation engine for explanatory math videos
plotext - plotting on terminal
volbx - Graphical tool for data manipulation written in C++/Qt.
bauh - Graphical user interface for managing your Linux applications. Supports AppImage, Debian and Arch packages (including AUR), Flatpak, Snap and native Web applications
termplotlib - :chart_with_upwards_trend: Plotting on the command line
