Using Microsoft Publisher to draw high quality flowcharts? Plenty of journals and magazines require high quality images when you get to submit a paper. 

I`m trying to get a simple flow chart of mine into a higher quality version. 

Is MS Publisher enough to do so ? I do not have any other "Corel Draw like" software .

What you think ?
You can use any software and later improve the quality of your chart with a vector software like Inkscape (or actually, you can draw the flowchart directly there). I could recommend you using Draw.io (https://www.draw.io/). It performs quite well, you can save your flowcharts directly to the cloud, and you can export your flowcharts in SVG format.
