The presentation discusses the importance of data visualization for data scientists in 2019 and the various tools available for web-based analytics sharing. It highlights several JavaScript and Python libraries that facilitate data visualization and emphasizes the use of libraries over handwritten code for most applications. The session promises to showcase practical examples and insights into these visualization tools.

This can be handwritten for simple or
exceptionally specific uses.
99.99% of the time, you should use a
library to interface to this.
