Article Summary of Data Visualization and Storytelling

In conducting data visualization and storytelling, three aspects are needed as a basis, namely, a strong foundation, the scenarios, and the last one is succeeding in the real world.

• A Strong Foundation

What is Data Visualization?

Data visualization is a visual or pictorial representation of the data. Often considered just a graphical presentation, data visualization includes a visual summary of information across images, charts, charts, and maps. In the field of data science, data visualization is recognized as the process of displaying data to provide insights that support better decision-making. That is, it tells the story behind the data. Data visualization is used to make it easier to understand and analyze data.

If we talk about data, there are several types of data, such as categorical data, ordinal data, and quantitative data. Categorical data represents things without any numerical data, ordinal data is similar to categorical data but has a clear order, while quantitative data is data that can be measured and aggregated.

Data can be visualized using charts. Chart is a graphical representation of data. The data represented is formed by symbols, such as bars, lines, or slices. Common types of charts such as Line Chart, Scatterplot, Bar Chart, Pie Chart, Choropleth Map, and Symbol Map.

There are 5 scenario points, namely:

1. Big Picture: Summary, objectives
2. Specifics: Details, features
3. Related Scenarios: Another related party
4. How people use the dashboard: Routine, strategic or operational
5. Why This Works: KPIs

• Succeeding in The Real World

In succeeding in the real world, several important points must be considered.

1. Make your own dashboard
2. Visualizing time
3. Beware the Dead-end Dashboard

To avoid dead-end tools, you should regularly review your dashboards using data. As you remove old ones, publish new ones, and adapt existing ones, you need to work closely with all stakeholders to make sure they are supportive and aware of the changes.
