polyscope

As highlighted in the README, Polyscope requires fewer than 10 lines of code to start visualizing, making integration incredibly fast for quick prototyping or debugging.

It offers consistent APIs in both C++ and Python, as shown in the code examples, allowing seamless use across different project environments without rewriting visualization logic.

Automatically handles boilerplate concerns like visibility toggling, color-mapping, and picking, enabling developers to focus on data rather than GUI implementation, per the features list.

In C++, template magic allows Polyscope to accept existing data types without conversion, reducing integration effort, as noted in the documentation link for data adaptors.
