SVG Generation in Ruby: A Practical Guide March 16, 2026 Recently, I created ruby-libgd and libgd-gis for raster graphics generation in cartography. But as I worked on these tools, I realized the landscape of web graphics has shifted significantly. Today's web demands interactive, scalable, responsive visualizations. That's where SVG (Scalable Vector Graphics) comes in. This … Continue reading SVG Generation in Ruby: A Practical Guide
March 16, 2026 Published on RubyStackNews After the last article, Jupyter proved to be an awesome sandbox for testing code interactively. I spent the entire weekend asking myself one question: can Ruby render a real 3D plot? I started convinced the answer was no. By Sunday night, ruby-libgd had proven me wrong. The question nobody … Continue reading Ruby for Data Science — Is It Possible?
Plotting Mathematical Functions in Ruby, Inside Jupyter March 13, 2026 ruby-libgd: Scientific Plotting Comes to Ruby The Envy We Never Talked About Anyone who has spent serious time with Ruby and then watched a Python developer type plt.show() to produce a beautiful Matplotlib graph in a Jupyter notebook knows the feeling. It is not quite … Continue reading Plotting Mathematical Functions in Ruby, Inside Jupyter
