About the talk:
Have you noticed in a World map, where, markers are used to represent something? The markers when seen at the beginning appear close between two locations and when zoomed in, appears far away. If the cities are too close it can even overlap each other. It will look ugly isn't it? In this talk we will explore the Quadtree approach which can be used to search for geometric points in a plane accurately and instantly and how this can be used in clustering.

🚀 🚀 🚀 Achieving Page Speed with a Data-heavy Data Visualisation

Presenter
Murray Bourne (@bourne_2_learn)

"I'm an educational consultant and have been developing various Web sites for over 2 decades."

About the talk:
Tableau Public is a highly recommended data visualisation platform, but its usability leaves a lot to be desired. Pages are slow to load; it's usually a disaster on a phone, and interactions are often clunky. This talk shows one way of achieving fast mobile-friendly pages that involve many images and a large amount of data.
