Hi, we are interested in using data2viz for a commercial project to generate some nice looking graphs :wink:
I would have following questions:
• do you have more information about the OEM licensing model (we have more than one developer, but we would generate the graphs on our backends not in apps)
• would it be possible to get some test licenses so we could evaluate if the integration for backend generated charts would work for us
Thanks

Hello <@U9T4T2HJP>,

The OEM licensing model is to integrate the library inside any application (front end or back end). We adjust our proposals to provide the best value with the proper support.

It’s possible to use the latest EAP versions for testing. See <https://maven.pkg.jetbrains.space/data2viz/p/maven/dev/io/data2viz/charts/core/1.0.12-RC1/> for example.

What kind of charts do you need, and what is the architecture of your solution?

We would like to add the charts to some reports we generate in our backend.
So basically we need to generate SVGs of the chart on the backend and then embed them into the generated PDFs.
Could you tell me which license we would need for that scenario?

It depends on the type of your solution:
• if it’s a SAAS -&gt; OEM
• if it’s a custom development for a unique customer -&gt; development license.
The main problem with your needs is that we currently don’t export in SVG. :wink:

We have it but mainly for testing support. We need to check if it’s possible to do it.

It’s a software developed for a unique customer so not SAAS.
• Would we need a separate license for every developer working on that project/service?
• Could we have this as floating license e.g. in that project we have x developers but they might change in/out during the year but constantly `x` developers?


Sorry, I missed your point. For data2viz, you don’t need any commercial license. It’s for Charts.kt that you need it.

However, in your case, Charts.kt can save you some time. See <https://charts-kt.io/>

If you take developer licenses for Charts.kt you can have `x` floating licenses.

Thanks

sorry I missed the difference between `charts-kt` and `data2viz` because when I go to `<https://charts-kt.io/try-it/> and then click `Browse examples, fork and edit code online` this leads to <https://play.data2viz.io/sketches?tag=charts.kt>.

Therefore the difference between those is not fully clear to me

Hi Dominik,
• Data2viz is the company name, and the name of our initial open-source library (<https://github.com/data2viz/data2viz>)
• Charts-kt is a commercial library based "on top" of data2viz, it allows developpers to create charts with much more ease

When you click on `Browse examples, fork and edit code online` it leads to an interactive developper notepad where you can try and code using data2viz and/or charts-kt.

TL;DR:
• if you need to make some very specific custom charts and know a lot about the datavisualisation techniques and stuff: use *data2viz*
• if you need to make charts based on standards (bar, line, area, plot...) with ease and speed: aim for *charts-kt*

Don't hesitate to send an email to <mailto:contact@data2viz.io|contact@data2viz.io> detailing your needs, project and stuff we can send you some precise information and feedback. Regards.
