A chart is a graphical representation of data, in which “the data is represented by symbols, such as bars in a bar chart, lines in a line chart, or slices in a pie chart”. Almost every development or project management team requires charts or graphs to understand and visualize the complex data and workflow for their web applications. Visualizing charts can help you to understand complex data easily which may results in improved productivity and reliability for your web applications & projects.
