Importance And Benefits Of Data Visualization

We generate data through all of our actions, not only from anything we do on the internet but also from anything we do in the offline world.

The data we collect is in either numerical or textual format, making it difficult to understand and find trends until it has been converted to visual forms such as charts or plots. This is where Data Visualization comes in.

In this blog, we’ve covered the benefits of data visualization Services, their uses for businesses and a step-by-step data visualization process.

What Is Data Visualization?

Data visualization is a method that uses static and interactive visuals to help people understand the large amount of data being collected. Data visualization is an important skill in applied statistics and machine learning.

It can be helpful when you need to get information from some datasets; the information we can mine from datasets can be about finding patterns, identifying outliers, and much more.

With some prior domain knowledge, visualization can be used to find relationships between the data, which can be insightful to you and your audience.

Benefits Of Data Visualization

It is difficult for humans to understand the data in numeric format because of its complexity and a large amount of data. That’s where data visualizations come into the picture, making it easy to understand the data and allowing decision-makers to act more quickly.

  • With the help of data visualization, decision-makers can easily understand how the data is being interpreted to determine business variations.
  • A large amount of data is handled and visualized to establish patterns. Many meaningful insights and the evidence behind the data can be used to establish a business goal.
  • Visualizing the data helps managers achieve growth and use new trend trends in business strategies.
  • Data analysts’ job is to make it easy to make new decisions for business development and expansion by using trends from the data with the help of healthcare data visualization.

Why Python For Data Visualization?

Python has evolved extensively in every field, be it Automation, Machine Learning, Testing, Scraping etc. Python has grown into a large community, further fueling the growth with new contributors and ecosystems.
Python has many visualization tools/libraries which provide excellent features and are easy to implement. It includes support for all types of visual, live, customized charts.

Worth mentioning, below are some of the most used python libraries for data visualization:

  • Matplotlib: It is a low-level library that provides much freedom to customize.
  • Pandas Visualization: Built on Matplotlib, It has an easy-to-use interface and makes visualization a breeze.
  • Seaborn: It has a high-level interface and also has great default styles.
  • Bokeh: Supports unique visualizations like Network graphs, Geospatial plots, etc.
  • Plotly: It can create interactive plots.

Step-By-Step-Data Visualization Process

To get the visualized data, you need to follow the below-mentioned steps:
Data Visualization Process | Mindbowser
  • Collecting Data

The first and most important step of data visualization is gathering data in large amounts. Only after we have substantial data can we apply data visualization techniques to the collected data and get some helpful insights from it.

  • Clean Your Data

Data cleaning is an essential step to perform before creating a visualization. A bunch of data out of a large dataset that has inappropriate, empty or false values may lead to adding erroneous visuals with anomalies in it.

The output received from a data cleaning process is usually a dataset that is free of errors and anomalies etc, which gives much more accuracy when data is processed. Data cleaning is pretty much dependent on the dataset domain that you’re working with.

  • Choose A Chart Type

Before choosing a visual chart or graph, it is important to understand your audience and choose a chart or graph that will best communicate the message.

Choosing a chart depends on what findings you need to convey to your audience.

  1. Do you want to show how merging data columns can give meaningful insights?
  2. Do you want to show some data patterns from the datasets?
  3. Do you want to show how data variables are compared to each other?
  4. Do you want to show the relationships between the data variables?

Choosing a couple of these can help to select the charts that will be best suitable for you. This usually requires some playing around with different charts before choosing the best.

  • Prepare Data

To prepare the data before sending it further for visualization is to determine the type of graph, chart or any other visualizations you need to create and the supporting library you will be integrating for it. After the chart is finalized, it may be necessary to transform the data as per requirements.

Data preparation tasks include finding data columns that help make some decisions, giving meaningful insights about data, grouping data, creating aggregate values for groups, combining variables to create new columns, etc.

  • Visualize Data

In the final step, you’ll have the required data to create visualizations. Now we apply visualization skills to the prepared data and represent the data in charts or graphs with meaningful insights. After we’re finished, we’ll present it to you so you can see what we’ve discovered!

Types Of Data Visualization Charts | Mindbowser


Now that we understand how the data visualization process works, we can apply different data visualization types to their uses. As mentioned in the earlier section, by using those visualizations libraries, we can create some visualizations as follows:

  • Line Chart

Line charts are used to display trends over time. The X-axis usually represents a period, and the Y-axis represents the quantity associated with the period on the X-axis. E.g., an A-line chart can illustrate a shopping mall’s peak visit time for the day broken down by weekdays and hours.

  • Area Chart

An area chart is a line chart with the areas below the lines filled with colors. Use a stacked area chart to display each value’s contribution to a total over some time.

  • Bar Chart

A bar chart also displays trends over time. In the case of multiple variables, a bar chart can make it easier to compare the data for each variable at every moment. E.g., a bar chart can compare the company’s growth year-wise.

  • Histogram

A histogram represents data using bars of different heights. Usually, each bar groups numbers into ranges in a histogram. The taller the bars, the more data falls in that range.

It displays the shape and spread of continuous data set samples. E.g., we can use a histogram to measure each answer’s frequency in a survey question. The bars would be the answer: “bad,” “good,” and “best.”

  • Scatter Plot

Scatter plots are used when there is a need to find correlations. If a data XY exists, then a Scatter plot is used to find the relationship between variables X and Y.

  • Bubble Chart

The bubble chart evolved from a scatter plot. Unlike scatter plots, each data point is assigned a label or category and shown as a bubble. It is used to show and compare the relationship between the labeled circles. A bubble chart makes it hard to read with multiple bubbles, so it has a limited data set size capacity.

  • Pie Chart

A pie chart is a circular graph representing the data set in which the pie slices are divided to represent a numeric proportion. Pie charts are used when there is a need to show the contribution of a data point inside a whole data set.

  • Gauge

A gauge chart is evolved from a pie chart and doughnut chart. It is used to visualize the distance between intervals. Multiple gauge charts can be shown linearly to visualize the difference between multiple intervals.

  • Map

Most of the data collected have a location variable, which makes it easy to plot on a map. , e.g., a map visualization is mapping the number of customers worldwide, country-wise, where each country would represent several customers. Location information can help businesses grow in a region where the business has not scattered compared to other regions.

  • Heat Map

A heat map is a visualization tool that uses color, like a bar chart’s height and width. Two dimensions are shown as a magnitude of a phenomenon. The heat map can identify whether the phenomenon is clustered or varies over space.
