Data Visualization :
Data visualization is the process of representing data in a visual format, such as a graph or chart. It allows people to understand and analyze data more easily, and make better-informed decisions based on that information.
One common example of data visualization is a line graph. A line graph is used to show how a particular set of data changes over time. For instance, a line graph could be used to show changes in the stock price of a company over the course of a year. The x-axis of the graph would represent time, while the y-axis would represent the stock price. The graph would consist of a series of data points connected by lines, allowing people to easily see how the stock price has changed over time.
Another example of data visualization is a pie chart. A pie chart is used to show the proportions of a whole. For instance, a pie chart could be used to show the market share of different companies in a particular industry. The pie chart would be divided into slices, with each slice representing the market share of a particular company. The size of the slice would be proportional to the company’s market share, allowing people to easily see which company has the largest share of the market.
Data visualization is an important tool for understanding and analyzing data. It allows people to quickly and easily see patterns and trends in data, and make more informed decisions based on that information. Whether it’s a line graph, a pie chart, or any other type of visual representation, data visualization is an essential part of modern data analysis.
