Temporal visualizations usually include all the events which were happened for a specific time or moment. Temporal data is characterized by items that have a start and finish time. These are some of the simplest ways to represent the data, which is essential. Some examples of temporal visualizations are Line graphs, stacked area charts, Bar graphs, Gantt charts, steam graphs, heat maps, and polar area diagrams. Illustrations of Temporal Visualizations include timelines, Gantt charts, stream graphs, arc diagrams/thread arcs, tree rings/concentric circle graphs, time series charts/graphs, and alluvial maps.

The line graph: Line graphs uses points connected by the lines to represent how a dependent and independent variable change. The Independent variable will remain the same, which means it remains unaffected by other parameters, whereas dependent variables depend on how the independent variable changes. For temporal visualizations, independent variables will always be time, and vertical axis dependent variables will be plotted.

Stacked Area Chart: It is similar to a line chart. However, in an area chart, multiple variables are “stacked” on top of each other, and the area below each line is colored to represent each variable. These charts are useful to show to show how both a cumulative total and individual component of that total changed over time.

Stream Graph: The graph looks like flowing liquid, hence the name.

Heat Map: Basically, the heat map is often used by the Geospatial visualizations as they quickly help identify hot spots of a given variable. When converted to temporal visualizations, heat maps can help us explore two levels of time in a 2D array.

Polar Area Diagram: Polar area diagrams represent seasonal or cyclical time series data, such as climate or seasonal crop data. Multiple variables can be neatly stacked in the various sectors of the pie.

Bar Charts: These are used to represent data more visually as horizontal or vertical bars. The length of each bar is proportional to the value of the variable then.

Gantt Chart: Gantt chart is a horizontal bar chart showing work completed in a certain period concerning the time allocated for that particular task.

 Hierarchical charts are graphical representations of an organization's structure. Hierarchical charts are based on the idea of ​​a hierarchy. Hierarchy is a system for classifying or ranking people based on ability or status (Wilke, 2019). A hierarchical diagram is described as a visual representation of a hierarchical system and is also known as a structural diagram (Kirk, 2019). Characters, titles or titles are clearly stated in an illustrated format showing the relationship between the elements. The top of the diagram is usually dedicated to the most important or significant part of the hierarchical system.  Its purpose is to describe the reporting relationships and command chain in an organization (Kirk, 2019). Employee names and titles and / or titles are usually drawn in rectangles or circles with lines connecting to other employees and departments. By looking at the organizational chart of the organization, people can quickly understand how the organization operates, how many levels it has and where each employee fits into the organization.

It is used when an object is in direct contact with another object and is also used to define its own characteristics (similar to the parent-child relationship). It allows the user to easily understand the whole work structure. It is used to define many real life examples, for example if there is a parent company and if it has different affiliates and all have different features. Information is displayed at different levels.

I choose hierarchical chart for discussion because it is the most simple and basic organization chart you can create in minutes. They can easily visualize the overall structure of the organization, its workload and identify key people responsible for specific tasks (Wilke, 2019). For example, you might consider this organizational chart, which indicates the hierarchical flow of employment within the organization.
