1 Data visualization basics

Data visualization is the process of transforming data into graphical or pictorial forms to make it easier to interpret. It can help you explain your system's architecture, components, and interactions, as well as show its behavior, state, and output. You can also use data visualization to compare your system's performance with other systems or benchmarks, find patterns and anomalies in the data, and highlight its strengths, weaknesses, and opportunities for improvement. When creating effective data visualizations, you should consider the type and amount of data, the audience and purpose of the visualization, the best format and style for it, and the tools and techniques you'll use.

In my professional experience, a visually appealing and well-executed visualization plays a pivotal role in a project. However, it's crucial to bear in mind the specific audience and purpose behind the visualization. The intricacies of creating a visualization are not to be underestimated. A poorly constructed visualization can lead to, at best, a lack of comprehension, and more often than not, it results in misinterpretation, paving the way for unforeseen consequences. The initial step is a thorough understanding of what needs to be depicted and in what manner. Subsequently, the selection of tools becomes instrumental. Opting for open and widely recognized tools ensures clarity and comprehension within the team and beyond.

Now a days, systems have become to smart that visualisation can be very very interactive. visualisation is the ultimate goal for data analysis. Think of drill down charts with interactivity while thinking of data visualisation systems.

2 Data visualization types

There are many types of data visualizations that you can use for your systems design project, depending on your data and goals. Diagrams, such as UML diagrams, flowcharts, ER diagrams, and network diagrams, are visual representations of your system's structure, logic, or flow. Charts, including bar charts, line charts, pie charts, and scatter plots, are graphical displays of your system's numerical or categorical data. Dashboards are collections of data visualizations that provide an overview of your system's performance or status. Maps, such as geographic maps, heat maps, and choropleth maps, are spatial representations of your system's data that show its location, distribution, or movement. These visualizations can help you illustrate your system's architecture and components; show its behavior, state, or output; compare its performance with other systems or benchmarks; and find patterns in your system's data.

3 Data visualization tools

When creating and presenting data visualizations for your systems design project, you have a variety of tools to choose from. Excel is a spreadsheet application that enables you to organize, analyze, and visualize your data. It can be used to create different types of charts, tables, and pivot tables. Additionally, it allows you to import and export data from other sources. Power BI is a business intelligence platform that helps you connect, transform, and visualize your data. It can be used to create interactive dashboards, reports, and charts. Tableau is a data visualization software that lets you create and explore your data with dashboards, charts, and maps. Finally, R is a programming language and environment that can be used for statistical analysis and data visualization with charts, graphs, and maps. All these tools can access and manipulate data from multiple sources.

4 Data visualization techniques

In order to make data visualizations more effective and appealing, there are several techniques that can be employed. It is important to choose the right type of visualization for your data and goals. For instance, bar charts can be used to compare discrete values, line charts to show trends over time, and pie charts to show proportions of a whole. Additionally, colors, shapes, and sizes can be used to highlight important or interesting data points. For example, bright colors can draw attention, different shapes can distinguish categories, and larger sizes can indicate magnitude. Labels, titles, and legends should also be added to provide context and clarity for your visualization. These elements can include labels to show the names or values of data points, titles to summarize the main message or purpose of your visualization, or legends to explain the meaning of colors or symbols. Finally, it is important to avoid clutter and noise that can distract or confuse your audience. This may include removing unnecessary elements such as grid lines, borders, or backgrounds; using consistent and readable fonts and scales; or limiting the number of colors or categories in your visualization.

I find the charts and graphs more attractive when they are in "Less is more" mode. Graphs, Charts & every data visualisation element should be interactive and should offer drill down (double click for more information).

5 Data visualization examples

When designing a system, it can be helpful to have some inspiration and ideas for data visualizations. For example, UML diagrams can show the classes, attributes, and methods of objects and their relationships. Flowcharts can illustrate steps and decisions in a process or algorithm. Bar charts can display frequency or distribution of input or output data. Line charts can show changes or variation in performance or quality metrics over time. Pie charts can depict composition or percentage of resources or components. Scatter plots can reveal correlation or relationship between two variables in data. Dashboards can present key indicators or measures of success or failure. Geographic maps can demonstrate the location or region of users or customers. Heat maps can show intensity or density of activity or events, while choropleth maps can indicate value or level of data by area or region.
