            [Dear ImGui Bundle](https://github.com/pthom/imgui_bundle) is a bundle for [Dear ImGui](https://github.com/ocornut/imgui.git), including various useful libraries from its ecosystem.
            It enables to easily create ImGui applications in C++, as well as in Python.
