If you are here, you are probably wondering about what a chart is, what a chart API is, and how to use one. Don’t worry, we will explain everything and give you the best recommendation to obtain the best results.
What is a chart?
A chart is a graphical representation of data that provides an overview and simplifies interpretation. Knowing how to read charts is important because they allow you to understand data more effectively.
There are several types of charts. In this article, we will focus on the most common charts – line charts, bar charts, and pie charts.
How do they work? The raw data is processed by a computer program (for example an Excel spreadsheet) before being saved in a specific format (for example .csv files) before being sent to the API endpoint that returns JSON objects. The JSON object is then received by the visualizer and then returned as an image file (or image base64).
The end result is an image that visualizes your data. You can save it locally or upload it to your website or blog.
What is a chart API?
The term “API” refers to “application programming interface” and indicates the presence of a collection of functions or procedures that allow or facilitate the development of applications by providing certain information or operating systems.
Chart APIs are those that allow developers to create charts directly from their application code without having to edit any code or write anything in Excel (like we said it above). This is great news because developers can save time and money by automating their processes and focusing on other aspects of their projects rather than on repetitive tasks like editing graphs.
What do they do exactly? As we said at the beginning, they generate images based on your JSON objects. And they interpret your data and then turn it into visually captivating charts.
The best Chart API in NodeJS right now is: Google Charts API.
Generate charts (images base64) based on your JSON objects. Be able to visualize your data with this API.
