  To aid the understanding of the non-linear relationship between galaxy
properties and predicted spectral energy distributions (SED), we present a new
interactive graphical user interface (GUI) tool pipes_vis based on Bagpipes
\citep{arXiv:1712.04452,arXiv:1903.11082}. It allows for real-time manipulation
of a model galaxy's star formation history, dust and other relevant properties
through sliders and text boxes, with each change's effect on the predicted SED
reflected instantaneously. We hope the tool will assist in building intuition
about what affects the SED of galaxies, potentially helping to speed up fitting
stages such as prior construction, and aid in undergraduate and graduate
teaching. pipes_vis is available online (pipes_vis is maintained and documented
online at https://github.com/HinLeung622/pipes_vis, or version 0.4.1 is
archived in Zenodo and also available for installation through pip install
pipes_vis).
