About

Map-based visualizations are an essential aspect of any data-presentation/ inference. Geo-spatial visualizations become all the more important for IoT companies like Carnot which have their devices scattered across different geographies. We at Carnot realized the need for having a robust map-based visualization infrastructure for all our present and future requirements. When we started building this infrastructure, we realized that there are way too many libraries available for map visualizations and several detailed tutorials for each library. However, what wasn't readily available was a comparison of the different libraries and a guide on which library is best suited for a particular application.

Hence, we started off with one library at a time, determined what it was best suited for, and then moved on to the next. We kept doing this exercise till we generated nearly all the types of visualizations we could envision. This repo is a helper repo for the series of Medium blog posts on map-based visualizations, where we share a summary of our learning during this entire exercise. It will hopefully serve as a guide to people who find themselves as overwhelmed with choices as we were at the start of our infra-building exercise.

Contributing to this repo

All suggestions, feedback and pull requests are welcome. However, please remember the context of this repo before submitting any contributions. This repo is intended to be a helper repo for the series of medium tutorial posts on the different map-based visualization libraries. At the same time, this repo and the blog posts intend to help the users identify the correct library for their user-case, out of all the available options. Finally, when introducing the users to a new library, the USP and the application areas of that library need to be explicitly made clear to the users. Your contributions should align with these objectives in kind and in spirit.
