According to our understanding, data visualization is a graphical representation of the information and the data that we like to present. We live in a modern world where we have to deal with a lot of data. And that is where the role of data visualization comes in. With the help of visual elements like charts, maps, and graphs, data visualization makes it easier and accessible to not only see but understand the trends and patterns in data.
Data Visualization is specifically used in areas like;
- Modeling all the complex events.
- Visualizing all such phenomenon which is otherwise impossible to observe directly like weather patterns, mathematical relationships, medical conditions, etc.
Why do we use it?
We use data visualization as it helps us to tell stories by curating our data into a form that becomes quite easy to understand. A good visualization is something that highlights useful information and then helps us make data-driven decisions.
Importance of Data Visualization:
Data visualization plays a vital part in our lives as it provides us with a really quick and effective way to communicate information in the form of visual information. This practice also helps businesses to identify the factors that affect customer behavior.
- Similarly, we use data visualization when we need to pinpoint all such areas that need improvement or rectification.
- Data visualization makes data a little less difficult to understand for the stakeholders. It helps them understand where to place a product and when is the right time to do it.
- With the help of data visualization, it becomes easy to predict sales volume.
Data Visualization Techniques:
Pie charts are considered to be one of the most common yet effective data visualization techniques. This type of technique is used in a wide range of applications. Pie charts are ideal for illustrating proportion or doing part-to-whole comparisons.
A Bar chart is another technique that is not only common but considered an easy-to-use method of data visualization. Here on one axis, we write the categories that have to be compared. On the other side, we put the measured values. Similarly, the length of the bar is going to indicate how each group is measured according to the value.
Through histograms, we can illustrate the distribution of the data over a continuous interval of time. These types of visualizations are helpful when we have to identify which values are concentrated. Similarly, histograms are also used to identify any gaps or unusual values.
Gantt chart is a type of data visualization that is mostly used in the field of project management. These charts come in handy while illustrating a project timeline or progression of tasks. All of the tasks that have to be performed are put on the vertical axis. Whereas the time intervals are listed on the horizontal axis.
