CARTO is hands-down the best geo-visualization tool in the industry. Beyond their stellar product, the executive and senior management team is one of the most thoughtful and engaged teams that I've collaborated work.

The ease of dropping in ESRI Shapefiles, Open Street Map data or all the other supported formats to quickly be able to visualize the information in a variety of ways. Their BI tools are great and constantly getting better and better through their continues integration. I also like that CARTO can be a database to manage projects and not only geospatial data. I also like that there are integration tools to many programming languages as well as QGIS.

one of the rare companies that do data visualization. they utilize a powerful tool with drag and drop tool from multiple of formats. price is a bit steep but governments can really use this.
