I released a new free tool that allows you to easily convert an Excel/CSV file into a JSON file for networks. It's available here: www.ladataviz.com/tools/jsonify It'll simplify the process a lot! If you have an issue getting additional quotes when copying the data from Tableau to the code editor, try copy-pasting first in Excel. This could come from different locale settings or operating systems. The end goal is the same: use Tableau to generate a string allowing you to build the JSON in its correct format quickly 🙂

@@IrisSunCoq There is no notion of 'level' in the network. Your countries, provinces, and cities are all nodes. And you have links between them. You can create an attribute "type" in your nodes to differentiate the countries/provinces/etc Maybe this will help: public.tableau.com/app/profile/zach.bowders/viz/AllofUs/_

For me, the hardest part was copying from Tableau :) For some reason, ctrl+c was not working well for me. I found it so much easier to download the nodes and links as a .csv file and copy-pasting from that to the .json file.

Thanks so much for your video Tristan! Love what this tool allows me to do. Question for you, do you know of a way to make a directional network? So that rather than simple links, there are directional arrows? I went down this rabbit hole when I was coding the JSON file with "source" and "target".

@ladataviz

Жыл бұрын

I *think* you should be able to do that in Tableau after exporting. Since a link has a type (source or target) you can identify the targets and maybe add a shape. The shape will not be an arrow (because I can't see how to set the right position) but it can be used to identify the direction.

Very nice and clever thankyou

For those that aren't able to copy the data from Tableau, I was able to work around this by saving the workbook to Tableau Public. Make sure to make your column with the custom calculated field wide enough. Then from Tableau Public, I showed all sheets and then downloaded the sheets I needed as PDFs.

Hi! Currently you have to regenerate a network with the tool if your data change. It’s something I’m well aware and it annoys me too! I’m trying to find a good way to automatize it. However if you already built your visualization you can just export the network in csv and simply refresh the data source in tableau instead of redesign everything ;)

It depends on your computer language and how it interprets the different quotes. For me, the attributes and string in JSON need double quote ". So to generate/concatenate the string in Tableau in need to wrap it in with a single quote '. Try it out with simple strings and copy and paste into VS Code to see the result. If you still have an issue, you can reach out to me on Twitter or via my website!

Do you mean that when you download the file from tools.ladataviz.com/network then you can not open it with Tableau Public? That is sadly normal as the exported file can only be opened with Tableau Desktop for moment (because the tool can't generate an hyper file). The good news is that next week I'll update the tool to allow you to download a Tableau Public working template + the generated data in CSV. You'll only need to refresh the extract of the template with the new data and you'll be able to publish it. I hope this answer your question!

You can't do it directly in Tableau, that's why I built those tools. They are not perfect but it's the best solution. If you need a network with data refreshed automatically I'd recommend not using Tableau. You can have as many types of nodes as you want. The only important thing with a network is to have list of nodes, and a list of links explaining the relation. Your node can have different categories.

There is no best way to create links. It'll depend on your data. The only rule is that all your source and target in the links must be nodes.
