Charts can generally be categorized into logic diagrams and data charts.
Logic diagrams are usually diagrams without specific data, and are used to express the relationship between concepts or processes. These diagrams are shown below.
Data charts are charts used to present data in a way that helps the user understand the data. There are three main types of charts that are most commonly used bar charts, line charts, and pie charts. In addition to these three types of charts, there are also scatter plots, radar plots, tree plots, waterfall plots, funnel plots, maps, and so on. Bar charts are one of the most commonly used charts by analysts and are often used to compare and vary across multiple dimensions. The textual dimension/time dimension is usually used as the X-axis. The numeric dimension serves as the Y-axis. Bar charts require at least one numeric dimension.
