Part 1: Introduction to Data Visualization
What is Data?
For some people, the data is simpler known as information about something. The contents in the data are indeed very credible because the data is a collection of facts that occur in the field. That is why data is often the reference needed when executing a marketing plan.
When explaining a company, you should not act solely based on your desires and estimates, visualizing the data you have must also be clear. When the percentage to the client valid data must be presented properly and correctly.
Beautifying through visualization so that data can be understood easily is one smart way and therefore every entrepreneur must be good at doing it. The ability to visualize data today is urgently needed to support a company.
If all data has been conveyed to all components of the company well and then they understand all the correlations, then just take good steps to create a business trend to attract consumers.
The essence of data visualization is to communicate information through graphic or picture means. In theory, images will be more easily digested by the brain than numbers, colors and shape greatly affect the speed of processes in the brain.
Therefore you must often see film meetings often using tables, graphs and so on. That is intended so that the audience can better understand the essence of the information presented in graphics.
Data === future
Why data is the future?
Yeah, it simple, just need accurate and valid data, we can predict what will happen in future. For example weather forecast from weather.com
Another benefits of data are also very much like for machine learning and also AI, without the data it would not have happened. Then with data, we can get about a situation or problem that exists in users.
Is enough with just a data?
If the data is only in written form it will be difficult to understand. For this reason, there is a visualization data in the form of graphs or diagrams, so data can be displayed more interesting and easier to understand
Okay Now it Shows Time 🙌
Actually there are my tools for making data visualization, but here I will share how to Visualize data with Grafana and Postgresql
What is Grafana and Why I used it?
Grafana is an open-source solution for running data analytics, pulling up metrics that make sense of the massive amount of data & to monitor our apps with the help of cool customizable dashboards.
Grafana connects with every possible data source, commonly mentioned as databases like Graphite, Prometheus, Influx DB, ElasticSearch, MySQL, PostgreSQL and another. This tool will help us study, analyze & monitor data over a while, technically called time-series analytics.
Another reason is that we can customize ourselves, how the data we create is visualized as needed and showing data with cool UI, easy to understand and very attractive
Ingredient
- Docker and Docker Compose
- Have been installed node js
- Basic Javascript
For easy to understanding, I will make this article into 4 parts
That’s all, if there is an error in code or if you have any suggestion please comment down below I will love to hear it :D
See you on the next part!
