I was testing something like this with https://sumostats.com/live (a second-screen style page, so you can quickly look up the current match and it follows along live).
But I think I know what you mean... I'll check out Natto graphics again (haven't seen it in a while) and will try make something up for next basho!
Every two months there’s a 15-day tournament where 670 rikishi(sumo wrestler) fighting ~160 matches each day. I’m recording all the results and kimarite (winning moves) into a browsable database with charts and videos.
Recently I have been using Gemini to process and edit the daily match videos. It works surprising well. It can detect the start/end of each bout, recognise the wrestlers and assign the correct rikishi id to them.
Still early, but if you want to get into Sumo feel free to join! Its fun to watch and the matches are quick!
Just a fun little site I made while waiting and checking the status of corona in Japan. I hope to keep it updated since I am checking the news and looking at the numbers daily anyway! Thanks for checking it out!
