Pygal is described as 'Dynamic SVG charting library written in Python' and is an app in the development category. There are six alternatives to Pygal for a variety of platforms, including Windows, Linux, Mac, Web-based and iPhone apps. The best Pygal alternative is Matplotlib, which is both free and Open Source. Other great apps like Pygal are GnuPlot, Plotly, Graph and python(x,y).
Matplotlib is a comprehensive library for creating static, animated, and interactive visualizations in Python. Matplotlib makes easy things easy and hard things possible.

Gnuplot is a portable command-line driven interactive data and function plotting utility. It was originally intended as to allow scientists and students to visualize mathematical functions and data. It does this job pretty well, but has grown to support many non-interactive...
Plotly is the easiest way to graph and share data online. Open-source libraries for JavaScript (comparison with HighCharts at https://plot.ly/highcharts-alternative/), Python, R, and MATLAB.

Graph is an open source application used to draw mathematical graphs in a coordinate system. Anyone who wants to draw graphs of functions will find this program useful. The program makes it very easy to visualize a function and paste it into another program.
Python(x,y) is a free scientific and engineering development software for numerical computations, data analysis and data visualization based on Python programming language, Qt graphical user interfaces and .
