What can you create?

2023 Advertising Spending by Industry (Four Major Media)

View the advertising spend scale across 21 industries and 4 major media types in a single chart. This type of chart is called a mosaic plot (or Mekko chart), which allows you to cross-tabulate two variables in one chart.

Distribution of Home Middle Schools by Prefecture for Koshien Tournament Players (Tohoku Region)

The left side shows Koshien participating schools, the right shows the home prefectures, and line thickness represents the number of players. Colored lines indicate movement within Tohoku, while gray lines indicate movement from outside the region. It can be created with a simple data format.

Popular Dog Breeds

Dog breeds are classified in a phylogenetic tree, with the size of the circles at the tips representing popularity. This is one of the chart types for expressing tree (hierarchical) structures. The beautiful data-driven curves are difficult to draw manually with design tools.

AirBnB Property Types and Accommodation Costs

3D maps are also easy to visualize. By simultaneously expressing multiple variables through color, size, and height, it becomes easier to grasp multiple aspects at once.

Efficiently Cleansing Name (Text) Data

You can cleanse data while viewing the full picture of variables.

Extract Table Data from a PDF by Specifying a Range

Easily convert PDFs published by government agencies and others into table data.

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

✅ 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.

✅ No installation required — everything runs in your browser

No software installation needed — everything is accessible through your web browser.

✅ 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.

✅ 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.
