Scatter Plot
A scatter plot is a type of data visualization that uses Cartesian coordinates to display values for two variables for a set of data. It represents data points as individual dots on a two-dimensional graph, with one variable on the x-axis and the other on the y-axis, allowing for the observation of relationships, trends, or correlations between the variables. It is widely used in statistics, data analysis, and scientific research to explore and communicate patterns in datasets.
Developers should learn and use scatter plots when analyzing and visualizing relationships between two continuous variables, such as in exploratory data analysis, machine learning feature engineering, or performance monitoring. They are essential for identifying correlations, outliers, or clusters in data, which can inform decision-making in applications like predictive modeling, A/B testing, or system diagnostics. For example, in a web application, a scatter plot might show the relationship between page load times and user engagement metrics to optimize performance.
