Install inkscape2tikz. The following example is taken from inkscape2tikz home page.
Using inkscape2tikz we export this in to tikz code:

Call this file as image.tex (say). Following is your main.tex file. Put image.tex and main.tex in the same folder. For this example, I have added image.tex by filecontents.
\documentclass{article}
\usepackage{graphicx}
\usepackage{charter} %%%% Added for demo of fonts Keep this in image.tex also to have same fonts
\usepackage{filecontents}
\begin{filecontents*}{image.tex}

This assumes that you have imagemagick installed.

This was a known bug in the Inkscape pdf export (which is used by the
svgpackage), see https://gitlab.com/inkscape/inkscape/-/issues/1984. The issue has been fixed in Inkscape itself (see https://gitlab.com/marcjeanmougin/inkscape/-/commit/9b5de7815fcd93c2801c7fb8703491125ef906b5) so at some point this will probably be picked up by Overleaf and the svg will render correctly.In the meantime the bug report also provided a workaround: replace all instances of
context-strokein the SVG source by a fixed color, for example#000000(black). In your SVG there were eight instances. I replaced them below:Then the conversion process does not crash anymore.
To make the LaTeX output a bit nicer I suggest to make the font small and sans serif:
Result:
To improve it further you can edit the SVG in Inkscape to center the labels, or even to export to a PDF directly from Inkscape and include the PDF with
\includegraphicsinstead of the conversion with thesvgpackage, then you have more control over the result.Note: I think the second node should be labeled Arduino and not Ardunino.
