Chart.js is a powerful data visualization library used for creating interactive charts and graphs. It is a lightweight, open-source JavaScript library designed to make data visualizations easily accessible to non-technical users. With Chart.js, developers can create a range of dynamic charts and data graphics for websites, web applications, and web-based data visualizations.
Data Visualization is the process of presenting data in visual formats, such as charts and graphs, to make it easier for people to understand and evaluate. Data visualizations created with Chart.js can aid in the analysis of complex data sets, making the information more comprehensible and accessible.
Charts and Graphs are the most common way people use Chart.js. These diagrams illustrate the relationships between different data points and allow the user to quickly analyze the data. Graphs are especially useful for exploring patterns and trends in data.
Pie Charts are circular diagrams with segments representing different categories of data. These charts are used to display the proportions or percentages of each data point in relation to the rest. Pie charts are particularly useful for showing changes in data over time.
Bar Graphs are a type of chart with horizontal or vertical bars used to compare different values or categories of data. These graphs are often used to compare two or more data sets, and can be especially useful for visualizing data that changes over time.
Radar Charts are circular diagrams that use multiple axes to display data. These charts are useful for displaying changes in different data points and are often used to show performance over time, such as trends in web analytics.
Scatter Plots are graphs that use Cartesian coordinates to represent data points in a scatter diagram. These plots are used to analyze and interpret data, as well as visualize data relationships.
Bubble Charts are data visualizations that use bubbles to represent numerical values. These charts are often used to compare multiple data sets, and can be especially useful for displaying changes in data over time.
