LibreOffice Draw

Draw has a noticeable bias towards business graphics: it’s very good in designing schemes, plans, sequences and charts, and it has a very solid bitmap tracing module. There are some tools for drawing freehand shapes, which enable you to effectively draw polygonal objects (for maps, for example), but there’s very little you can do with nodes and objects intersecting. It is clearly targeted at making simple shapes and organising relations between them, so you can group objects, draw beautiful linking arrows and arrange objects, but it’s almost impossible – or at least very hard – to draw a photorealistic image. Draw is very good at simple graphics and reasonably capable for sketches and drawings, making it a great choice for business graphics, but even these could be enhanced with more artistic tools such as brushes and external effects.
