Heya graph

Recommended Posts

Posted (edited)

Hello everyone! I've made this graph website visualizing all active heya's rikishi and sekitori. SumoDB was the main source of data and the Japanese Wikipedia was useful as well. I am planning on adding past heyas too, so stay tuned. And don't forget to check out the Information tab on the bottom of the page for graph info

Nice work! (Applauding...)

I take it that only the current instances of heya are present, e.g. Futagoyama starting at 2018.05 when it was re-established by Miyabiyama.

That's right. And I will add the previous Futagoyama and many other closed down heya in later update, I hope many would like to see them

Nice work!

One suggestion - perhaps consider adding some functionality to group heya by ichimon?

Like a toggle button to switch between alphebetically ordered and Ichimon-grouped heya name layout? I think I can do that

Interesting!  The first thing that caught my eye was the ~50% reduction in rikishi at Isegahama and Sadogatake over the last five years.

The site has been updated to add heya that shut down since WWII. A few short-lived heya had little to no data in the DB (like Asashio III's Furiwake beya) so they weren't included. You can also sort heya names now.

I now understood Seiyashi's suggestion. I feel like I should add individual graphs for each ichimon. But I don't know how to implement that yet.

More suggestions and feedback are most welcome https://chiyotasuke.github.io/heya-graph/

I apologise for being that one guy who's just creating work and not doing it, but if you deliberately select heya that have an intertwined history, you actually get to see, in a somewhat abstract form, the actual movement of rikishi as splitoffs and mergers happen. For example, the infamous Fujishima-Futagoyama merger, and then the absorption of Takanohana into Tokiwayama.

Perhaps it would help if, instead of the previous names and shishos turning up only after a heya is selected, they would appear when you moused over the heya before selecting it? That would definitely be a massive help to anyone using your graph as an accompaniment to e.g. @Asashosakari's occasional rabbit hole spelunking into heya and kabu history.

These are very great ideas. I think it's crucial to show the heya merging, splitoff and such things in the graph to really illustrate the history of the heya. The whole thing needs to be informative yet easy to understand. I also thought of making tooltip with past names and shisho that show up upon hovering over heya names. I'll try to implement them all, but as I'm not that experienced in coding it'll take longer to finish

Selecting Futagoyama still doesn't show the prevalent era.

It's shown under Takanohana. Do you feel like it's unfair for the previous Futagoyama to be shown that way? My graph sucks a little in that aspect

No one asked for this, but I just made one for shusshin. Could've made this sooner

I would've asked for it if I'd thought to. Very well done! This instantly answers my question about when school graduate entries became the fashion.

Interestingly, in the 50s and 60s the northern prefectures dominate (Hokkaido, Akita, Aomori) while in the 80s and 90s the cities dominate (Aichi, Fukuoka, Tokyo, Osaka) - influence of the tournament locations taking over from the traditional sumo stock?
