Using SVG icons in your map improve the possibility to customize it. In this video is shown how to increase the QGIS icon set.
My favourite icons website is The Noun Project, where you can find a lot of different icons, vector and raster.
Icons are really important for good visualisation of data, but it’s not easy to select them correctly. For sure, using SVG icons, you optimize the production and after collecting them you’ll be able to use them every time you create a map.
