Generation of output files

[Neriderc]

Do any of the Vis.js libraries allow for output of files like JPG, PNG, PDF, etc replacing that functionally in GraphViz?

I'd like to be able to move a site away from needing GraphViz installed on the server but this is the last functionality I haven't resolved.

@Neriderc did you ever manage to migrate away from GraphViz?

@Neriderc did you ever manage to migrate away from GraphViz?

I did get off using server based GraphViz, yes, using viz.js (different from this visjs repo). Unfortunately using an old version as I wasn't able to migrate to the new one (perhaps due to a lack of effort).

With the SVG output, I'm drawing it to a canvas element in the browser then downloading this data as a JPG or PNG. I also have PDF half-working, by saving the image into a PDF file using jsPDF (this is not as good as the native PDF created by GraphViz).

I actually detect if GraphViz is installed on the server, if so I use it, if not I use the browser setup.

Uhm, so, did you ever use vis-timeline or were you "just" trying to replace GraphViz with an alternative in the browser?

[Neriderc]

I was just trying to get a way to show a diagram and be able to download it as a file using the browser. I didn't get an answer to this question so never progressed very far, instead working out how to use the GraphViz-compiled-to-JS project as above.

If it's rendered on a canvas (e.g. Vis Network), it can be downloaded using native browser APIs (https://developer.mozilla.org/en-US/docs/Web/API/HTMLCanvasElement/toBlob). Unfortunately Vis Timeline is built using DOM elements and there is no easy way to export it into anything else.
