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.

Does this sound like your data workflow?

• You discover useful chart types, but your current tools don’t support them
• Excel only covers basic charts, making your output feel repetitive
