Data is a significant asset for any business, and we have access to enormous amounts of data!
Yet, we need tools to process this data to take advantage of it, and here it comes data visualization.
This article will explain its concept, how it works, its importance, and the languages used for it.
Are you ready to capitalize on your data?
Data Visualization (DV) encloses recasting information into a visual context.
For example, a map or graph can make it easier for our brains to process and understand the data.
This approach, in turn, helps us pull valuable insights faster.
Data visualization is particularly convenient when dealing with large data sets.
Visuals ease pattern identification within big chunks of data.
Data visualization and data analytics are both fields within Data Science.
While visualization shows data visually, analytics studies it to get actionable insights.
You could say data visualization is one of the tools used in data analytics to get better insights.
About its workforce, data visualization falls into the skills of data engineers. Meanwhile, data analysts are responsible for analytics.
As we've seen before, Big Data pulls unique insights with massive data collections.
The amount of data usually exceeds the traditional database software's analysis.
Due to simplifying analyses, data visualization has become a vital tool for Big Data.
Also, it helps present information collected from Big Data faster.
Yet, these scenarios need more complex representations, like heat maps and fever charts.
Proper Big Data Visualization requires a specialist, IT, and management involvement.
Given the amount of data, it is also essential to install quality control practices.
There are a lot of different techniques when it comes to data visualization.
Below, we'll look at Noah Illynsky's four pillars of effective data visualization.
We'll also check use cases and techniques to get you started.
According to Noah Illynsky, there are four pillars to achieving effective data visualization:
Heat Maps use color variations to display data and help identify trends.
Scatter Plots show the relationship between two variables on an x- and y-axis, with dots as data points.
Likewise, as a variation of scatter plots, bubble clouds use different circles in a two-dimensional field.
Pie Charts are easy to read and help illustrate proportions.
This technique is one of the most common for data visualization.
Line Charts show how variables change over time.
Bar Charts or graphs are also quite common. They apply mainly for comparisons.
Likewise, Gantt Charts show project timelines or task progression.
There are several ways to show populations' subgenres in data visualization.
For instance, Population Pyramids use stacked bar graphs to illustrate a population's distribution.
Pyramids break down the population by age and sex group, also enclosing Choropleth Graphs.
These show numerical values for specific geographical regions using color, shading, and patterns.
Choropleth graphs help viewers see how variables change depending on the area.
Histograms show data distribution over a period, and are great for seeing the frequency of a specific occurrence.
Also, Treemaps show hierarchical data through nested figures, comparing parts of the whole when having many categories.
Timelines help picture events in chronological order. While simple, formatting them can make data stand out.
For businesses, Bullet Graphs are a fantastic way to show performance.
It includes the actual and target values for a specific business metric.
Also, Area Charts are line chart versions showing many values over time.
These are great for showing changes in quantities over a set period.
Last but not least, Correlation Matrices display correlation coefficients between variables portray relationships.
Developed by Guido van Rossum, Python is part of the general-purpose languages category.
On Data Visualization, Python is well-suited to handle massive amounts of data.
You can use it to build deep learning models and perform non-statistical tasks.
Also, you can combine it with several DS libraries, like Matplotlib, Keras, and TensorFlow.
R is a statistical programming language and a software environment.
With powerful graphics and cross-platform compatibility, R doesn't need a compiler.
Also, it has a robust ecosystem with extensive statistical packages, such as ggplot2, Leaflet, and Plotly.
R is also great for building statistical models and creating graphics.
Netscape created JavaScript (JS) as a lightweight programming or scripting language.
JS is also object-based, general-purpose, dynamic, and interpreted.
JS is less popular for data visualization than R and Python, yet it has excellent libraries!
Some examples are D3, Charts, and Victory.
As you can see, Data Visualization is a big part of Analytics.
It's especially relevant in a world where data multiplies by the millisecond.
Visualization simplifies data so businesses can make better decisions faster.
