Span chart, also known as a range bar graph (range column graph), floating bar graph, difference graph, high-low graph, used to display the specific variable value range. Span charts are ideal for comparing ranges, and typically, each variable represents a particular category. All values for the selected category fall between minimal and maximal values that correspond to lower and upper bounds of the interval.

For some charts or diagrams, you need to create a regular polygon – equiangular (all angles are equal) or equilateral (all sides have the same length). E.g., equilateral triangle, regular square, etc.

When you create a shape in your spreadsheet, it is created with the default style and any text that you type has the default font.

A flow chart usually shows steps in a task, process, or workflow. There are many different SmartArt templates predefined in Excel that you can use to illustrate the process, including some complex templates with pictures.

A flowchart or flow chart usually shows steps of the task, process, or workflow. There are many different SmartArt templates predefined in MS Excel that you can use to illustrate the process, including visually appealing templates with pictures.
However, if you want to use different shapes and a complex topology, it is better to create your own flowchart.

Most process flow diagrams and workflow charts use elbow connectors for connecting process stages and elements, but too many connecting lines of the same type give your chart a messy look. Fortunately, you can combine different connector types that represent semantically different transitions.

When you create the process flow chart, process map, business flow diagram or data flow diagrams, and UML activity diagrams, you often need to add some text or labels to the connectors. Unlike other free and commercial diagram drawing packages, Microsoft Office shapes provide extremely rich text formatting features.

Business process charts like employee routines, document preparation and approval, or online user navigation path on a website or a Web store are different from academic flows of algorithms. Usually, academic applications use a limited number of standard shape types, but in business, different shapes give a better look and simplify understanding. However, it is hard to decide which shape is appropriate for the specific block.

The Format tab of the Drawing Tools toolbar provides a plenty of options for customizing a shape outline, background, and text settings. Also, you can change spacing and size for multiple shapes at once.

Every time you add, move, or resize shapes, by default, it isn't easy to align them. Excel proposes features named Snap to Shape and Snap to Grid that can help to organize shape and any objects.
