Data Visualization using different chart types
In today’s world, numbers are essential for any organization to get a 360 degree view of what the company’s current position is and also to aid decision making to attain future milestones. Top CEO’s want to get a dashboard view of different KPI’s on a daily basis rather than viewing complicated reports on Excel!
Let me take you through the different types of charts that I generated as a Client Case Study using ZEPTO — an AI powered analytics tool, which literally means a factor of ‘10 to the power -21’.With Zepto you can delve into the depths of your data and make business decisions based on facts and figures and not just opinions! Just to give you an overview — the data set was of a financial services organization which provides assistance with procuring various financial products, loans, credit cards etc. A separate customer service division would provide assistance to users, helping them with any issues and to help resolve complaints if any.The different charts generated are as follows:
1. BAR CHARTS:
A chart where bars are used to show comparisons between categories of data is called a bar chart. In a bar chart you need at least one dimension and one measure. The bars can be either horizontal or vertical. Bar charts are easy to understand, widely used, and can show changes over time. The vertical bars have lengths that are proportional to quantities they represent. It is usually used when one axis cannot have a numerical scale.
The different types of bar charts are as follows:
Vertical Cluster Bar chart:
Horizontal Cluster Bar Chart:
A stacked bar chart is a chart that uses bars to show comparisons between categories of data, but with ability to break down and compare parts of a whole. Each bar in the chart represents a whole, and segments in the bar represent different parts or categories of that whole. A stacked bar chart is of the following types:
Vertical Stack Bar Chart:
Horizontal Stack Bar Chart:
A 100% stacked bar chart shows the relative percentage of multiple data series in stacked columns, where the total (cumulative) of stacked columns always equals 100%. The different types of 100% stack bar charts are as follows:
Vertical 100% Stack Bar Chart:
Horizontal 100% Stack Bar Chart:
2. Line Charts:
A line chart is used to visualize changes over the same period of time for more than one group. This chart can be effectively used to identify a trend or pattern in data, like seasonal effects and massive changes over time.
3. Area Charts:
Area charts depict a time-series relationship. What makes it different from line charts? The answer is that area charts can also visually represent volume. Information is graphed on two axes, using data points connected by line segments. The area between the axis and this line is commonly emphasized with color or shading for legibility.
4. Pie Chart
Pie charts are generally used to show percentage or proportional data . We can determine the percentage represented by each category by hovering over the corresponding slice of pie. Pie charts are best to use when you are trying to compare parts of a whole — however they do not show changes over time. It is not advisable to use a pie chart when trying to measure changes over a period of time.
5. Basic Table:
Details of the categories are displayed in a table format as shown below. This table again does not show any changes over time
6. Digit Box:
Digit box will give a standalone value for one parameter. The following examples gives a sum of all the issues which were recorded by the organization.It is especially useful to monitor KPI’s on a dashboard.
7. Combo Chart:
A combo chart is a chart that combines two or more chart types in a single chart. Combo charts are useful where you want to validate the relationship between two variables that have different magnitudes and scales of measurement but are related in a meaningful way. Combo charts are most useful for following trends and identifying outliers in the data that may require further investigation.
The charts have been generated using ZEPTO ( https://www.zepto.io/)
