Clicking on a #hashtag shows the instances it was recently used on.

Clicking on a instance shows the hashtags that were recently used there.

I am investigating why there are instances missing. Could be a problem with data collection or export.

I found some problems in yesterdays data. Primarily caused by a bug in the code (same Toots were collected over and over). I updated the Gist with the fixed code. https://gist.github.com/lucahammer/8e31fa100446c3b7c783a00bd006003a

For todays run I used my own list of #mastodon instances which I collected for the #fediverse visualization: https://vis.social/@Luca/100606625507856187

@Luca Used this to explore hashtag usage and find someone to follow on another instance I never would have encountered otherwise. 👍

@Luca

Very cool!

When you select an instance and get the Information Pane on the right, what's the sort order for the hashtags listed under "connections"? It doesn't appear to be the most commonly used hashtags

@codesections To be honest: I don't know. I used the default sigmaJS Exporter in Gephi and only tweaked some settings.

@Luca

Thanks. Another question: what do the colors of the lines mean?

@codesections They indicate clusters. Calculated by the Modularity algorithm. Because of the mixed nodes, not very meaningful.
@Luca Controls not working and scrolling is buggy on Acer Chromebook Tab 10. (Performance is fine.) Probably expecting mouse events on desktop browser?
@unextro Thanks for the report. I can reproduce the issue on a touchscreen device. Not sure if I will be able to fix it.
You can use http://www.unmung.com/mastoview?url=s10y.eu&view=local to preview local timelines. I hope that it will some day possible to visit/pin them from within tootsuite and other clients.
@Luca
you can pin a instance with the mastalab app, available for android

@Luca
Well I guess a few bots and a few fetishists can really impact these top stats.
@Luca is there a new searchable map yet? Clicked the link in your previous toot and it took me to messages from 6 days ago
@zcampau Not yet. I am still working through the new data, live tooting findings and hopefully releasing an interactive version in the end.

@Luca

Once this gets a few more instances from my corner of the #fediverse, it will be very cool!

(Sadly, it currently seems to be missing most of the #tech/#foss/#linux section of the 'verse)

@codesections I am collecting new data as we write. I found a bad bug as well, which probably caused me to only get 40 Toots per instance. And I switched to using the instances I collected myself.

@Luca
Doesn't seem to work on Ff-mobile, but on desktop it worked great. I saved to myself. Saw some of my tags.

Very cool.

@Qwxlea It needs WebGL to work. While it should work on most mobiles, it isn't very usable.

@Luca
No problem, a mobile screen is too small anyway to effectively see anything.

*really* enjoy seeing all your wizardry floating by.

@Luca Yes, todon.nl is clearly missing.
@jeroenpraat It was in the seed list. Not sure why it didn't make it into the visualization.
@Luca Hopefully it will be in the next revision.
