Does this sound like your data workflow?
- You discover useful chart types, but your current tools don’t support them
- You’re exhausted by preprocessing before you even get to visualization
- Extracting tables from PDFs is a struggle every time
- You have address data but can’t plot it on a map
- Data processing in Excel has become dependent on specific individuals
- There are large skill gaps within your team when it comes to data
Four key features that solve these problems

Four key features
β Unlimited access to over 40 types of tools
From chart creation, map display, and color design to specialized visualization expressions. Data processing, formatting, and conversion tools are also included.
β No installation required β everything runs in your browser
No software installation needed β everything is accessible through your web browser.
β Single-purpose tools that are easy to learn and use
Each tool is focused on a single function. This dramatically reduces the time spent learning complex operations and configurations. We prioritize simplicity so that teams with varying levels of data literacy can start using them right away.
β Seamlessly switch between visualization and processing
To tackle various visualizations, you need to prepare data suited to each purpose. Visualization alone or processing alone is rarely sufficient. We provide a visual environment for trial-and-error data preparation for visualization.
