dfvue is a minimal GUI for a quick view of csv files. It uses an input panel similar to Excel to check visually that the csv file is read correctly. It provides most options of pandas.read_csv to be very versatile on possible csv formats. dfvue is a Python script that can be called from within Python or as a command line tool. It is not supposed to produce publication-ready plots but rather provide a quick overview of the csv file. The complete graphical documentation is available at Github Pages. Version 3.0 uses CustomTkinter if installed, otherwise the Azure theme of rbende for conda environments, for example. Version 4.0 allows reading multiple csv files that will be concatenated. Version 5.0 adds the possibility to manipulate the DataFrame, and allows resizing of plotting window. Version 6.0 provides standalone packages.
