Chapter 12 discusses five principles for making a graphic clear and understandable. One principle is that the graphic should have a purpose. What is another principle for making an effective graphic?

Another principle for making an effective graphic, in addition to having a clear purpose, is to ensure that the graphic is well-organized. This means that the elements within the graphic should be arranged in a logical and coherent manner, allowing the viewer to easily follow and understand the information being presented. A well-organized graphic often uses a grid system or aligns elements in a way that guides the viewer's eye through the content in a structured way.

Here are some key aspects of a well-organized graphic:

1. **Hierarchy**: Establishing a visual hierarchy helps to guide the viewer's attention to the most important elements first. This can be achieved through the use of size, color, or placement on the page.

2. **Simplicity**: Avoiding clutter and unnecessary details can help to keep the focus on the main message. A simple and clean design often communicates more effectively than a complex one.

3. **Consistency**: Using consistent styles for similar types of information (like color-coding or consistent font usage) helps the viewer to quickly understand patterns and categories within the data.

4. **Alignment**: Proper alignment of elements can create a sense of order and improve the readability of the graphic. This includes aligning text, images, and other visual elements both vertically and horizontally.

5. **Legibility**: Text and data within the graphic should be easy to read. This includes choosing appropriate fonts, font sizes, and colors that contrast well with the background.

By focusing on organization, designers can create graphics that not only serve their intended purpose but also provide a seamless and intuitive experience for the viewer.
