I’ve created a small web app called Taxonomic Tree. It shows a taxonomic tree diagram of species within a chosen taxon and place, using data from iNaturalist. You can select whether to display the top 15 or 30 most common species, and click on any node to open a popup with more information about th…

Looks very nice and it has lots of potential! I would like to have options: to zoom in - out the tree, export tree to a pdf. Also, it would be amazing to have a feature to compare two taxons and see the smallest clade containing both taxa. I’ve been looking for a simple-to-use tool online for that…

[image] wooden_box: ’m in the process of refining the app, and there may still be some bugs. Feedback is appreciated, and I’m open to adding support for other languages. I can see the common name in my language. Is this taken from the iNaturalist locale? I cannot refer to it with an url, can…

Hi @povilasgibas , Zoom should be doable. I’ll see if I can work something up in the next few days. PDF export will be difficult, a simpler alternative would be a svg image export. Getting the smallest clade from two taxa will be out of scope for this app. But you should try https://labs.minutelabs…

Hi @optilete The language is being set by looking at your preferred language in your browser settings. Then it shows the common names for that language from iNaturalist. I’ll add the URL queries for place and taxon in a few days. I was originally going to do that, but I left it out so I could get…

Sorry, thought my browser was English, but this one is not… Nice to play with, but I am not sure if I will use it.. There should be a database of stuff build on the API of iNaturalist. Maybe a separate forum item Tools/Apps/Software.?

Yeah, the thread for this app was suggested to me after I posted. The rendered tree is quite similar in both apps. But I want the tree to be based on location rather than user. I’m most interested in being able to view taxa in different locations, so it gives me a reference point for species identi…

That’s really cool! I quite like it. Something to correct though - only genus and species names should be italicised, with everything higher (tribe, family, order, etc.) not italicised.

[image] wooden_box: I want the tree to be based on location rather than user. i don’t think there’s anything about the other thing that precludes it from being modified to handle either users or places or both. unless there’s something that you really dislike about that other thing, seems lik…

Hi @matthew_connors thanks for the call out. It looks like this will apply to animalia, but not fungi or plantae. If this sounds correct I can update it.

ranks above genus are not italicised in fungi or plants either
