Vega-Altair is a powerful toolkit for creating interactive and engaging geovisualisations in Python. Lets talk about it.
Hi! This talk is about Vega-Altair and its capabilities for geovisualisations. I will start with discussing the background of Altair and and how it relates to the grammar of interactive graphics. Then, I will show you the capabilities of Altair, starting with simple geovisualizations and gradually moving on to more complex, interactive ones. It's going to be fun!
Vega-Altair is a python library that follows a declarative visualization grammar that allows users to create interactive graphics in a simple and intuitive way. We will touch upon Vega-Lite and show why this is a powerful toolkit for creating geovisualizations.
During my talk, I will show you how Altair integrates with the geospatial ecosystem in Python, but also in the wider ecosystem of web applications. I will present how to create a variety of geovisualisations. From simple maps to more complex. I will demonstrate the mapping of polygons, points, lines, choropleths classifications, small multiples, customisation of appearance and interactivity.
I hope you will join me for my talk on Altair and its capabilities for (geo)visualisations. I'm sure you'll come away with some new skills and ideas for creating interactive, engaging geovisualisations in Python. See you there!
