Flow Chart
FlowChart is a vector drawing application for Windows. Drawing objects include basic shapes, text, images, and lines. These objects can be grouped, aligned, resized, and nudged. Drawing objects can be organized into layers and the document can be viewed at different zoom ratios.
FlowChart can illustrate engineering-related diagrams such as flow charts and experimental setups, as shown above. For general illustration, Adobe Illustrator or Inkscape are preferred.
