r/datavisualization

I’ve been trying to make cleaner, more readable graphs lately and realized most default tools don’t look that great out of the box.

Excel works, but it often ends up looking… basic.

Some tools look better, but take way more effort to learn.

So I’m curious what people actually use in practice:

• what you consistently go back to
• what gives you good results without too much friction
• what you’d recommend to someone who cares about how charts actually look
• Bonus if you’ve switched tools and noticed a big difference.

tl;dr: I built One Piece of Data

Hello r/OnePiece

I have working on this personal project named One Piece of Data for the last 3 years. Starting as a personal and my own happiness/objective, now I try to share with my fellow nakama :)

Sichibukiai's Appearance Timeline

The idea is very simple, I want to explore One Piece from a data perspective, where I can search something quickly, filter something, aggregate something, and eventually vizualise it.

Fortunately, we have One Piece Wikia that contains this information in more structured form, but obviously still text based. With its API, I collect the data, clean it, and store it in a database. From here, the possibility is endless.

So, what is is:

Recurring and New Characters per Saga

Explore

• Characters — sortable/filterable table (by saga, arc, chapter, time-skip, status, affiliation, etc.) with detail pages covering bio, appearances, devil fruit, haki, affiliations, and occupations
• Devil Fruits — grouped by name + model, with type/sub-type filters and every known user
• Affiliations & Occupations — rosters with status breakdowns (e.g. who in the Marines is alive vs. defeated)
• Sagas / Arcs / Volumes / Chapters — cross-linked, with featured character portraits

Analytics dashboards

• Bounty rankings, demographics, appearance counts, story pacing, data-quality stats. And the connection between them.
• Character Compare — pick any two characters and diff them side-by-side
• Character Network — interactive graph of who interacts with who
• Timeline & Appearance Race — watch screen time accumulate across the run
• Word Cloud per character
• Chapter Release Predictor — forecasts upcoming Jump issue release dates and break weeks

Games

• Guess the Character (image quiz) and Who Am I? (progressive hints), with local score tracking and shareable result cards

Appearance Race with 30 chapter window

There's also a global search and an AI chat assistant if you'd rather just ask questions. You need to register (and I need to enable it for you) because the LLM is expensive. It's still a beta.

Obviously, it's far from perfect or complete. The manga is still running. The Wikia is not 100% complete. And my data preparation/cleaning is not perfect. But, I believe it's good enough to see something beyond reading chapter by chapter. I will try to update it 1-2 days after a new chapter is released.

I will try to share some visualization or finding. For example: the result from World Top 100 Popularity or the interesting connection between blood type and strength.

Enjoy! and tell me your suggestion of data or vizualisation that you want to see!

PS: Dang, I am not planning to release it in the same time as u/OharaLibrarianArtur map. I admire him.

I would appreciate an honest review on this matter.

Journey to the West (西游记) is one of the greatest epics ever written and I wanted to see what the whole thing looked like as data. Every character, location, and story arc across all 100 chapters, explorable in one place.
