I designed the charts, and am glad you appreciate them! I just used Adobe Illustrator, which is one of the best graphic design/vector-based programs. But in terms of creating something similar, it’s a bit more about learning some graphic design than it is about knowing any particular set of steps or software.
It’s not super hard to get good at making clean and clear data visualizations. I encourage you to just try some not-too-limiting software (like illustrator), arm yourself with it’s user manual, some youtube tutorials, and references of visualizations you think are pleasant, and then simply play with some of your data to try and make it feel pleasant.
