The company behind the popular data visualization tool CartoDB is increasing storage space for free accounts by 10 times, providing users with up to 50MB of space to create and upload maps. This change aims to make it easier for journalists, NGOs, and businesses to start using CartoDB's features such as styling wizards and geocoding tools. The expanded free account will allow new users to explore the full potential of CartoDB without restrictions, while also offering paid accounts with increased privacy controls and more advanced features.
