HoloViews is a high-level plotting library for Python, which create interactive plots with simple syntax and minimal efforts
For data visualization, there are many libraries in Python. In some of previous posts, some Python libraries for data visualization have been discussed, such as three systematic posts on Matplotlib data visualization, Rotate Axis Tick Labels in Matplotlib, Interactive 2D and 3D plots with Matplotlib, and Interactive 2D and 3D plots with Plotly. If you are interested in data visualization from this basic libraries, you can read these posts first. Otherwise, go ahead to read the post.
