ぷらっとmapくん-patent data graph generator

Example

A user uploads a patent dataset that includes columns like patent number, application date, and FI classification. ぷらっとmapくん generates graphs that display the distribution of patents over time, classified by FI categories.

Scenario

A company is analyzing its competitors' patents in a specific technology area. They use ぷらっとmapくん to generate a timeline graph that shows how patent filings have increased or decreased over the years in that specific category.

Example

The uploaded dataset includes FI classification codes in a single column, separated by commas. ぷらっとmapくん applies a custom preprocessing method to split these entries correctly and ensures that the FI codes are parsed accurately for visualization.

Scenario

A patent office researcher uploads a dataset where each patent includes multiple FI classifications. The tool splits the classifications appropriately and then generates a bar chart showing the most common classifications in the dataset, allowing the researcher to understand technology trends.

Example

To ensure that visualizations display Japanese patent information correctly, ぷらっとmapくん uses a specialized font ('ipaexg.ttf') for rendering Japanese characters, ensuring legibility in generated graphs.

Scenario

An intellectual property (IP) analyst working in Japan uploads a dataset that contains patent titles, applicants, and FI codes in Japanese. ぷらっとmapくん generates a set of pie charts and bar charts with proper labels in Japanese, allowing the analyst to present the findings in a Japanese-language report.
