I know how to make the diagram in Visio have a transparent background. I go to File > Export, then save as a .png and tick the box to enable transparency.
But when I insert that png image in to a Power point presentation on to a slide with a colored background then the Cause and Effect diagram looks terrible and blurry.
How can I make the diagram appear sharp like it appears in Visio but with a transparent background so it look good on the Powerpoint presentation?
Any help much appreciated.
