Which of the following provides a graphical overview of a project?Select one:a.Pie chartb.Gantt chartc.Line graphd.Dot graph

To answer this question, let's analyze each option:

a. Pie chart

• A pie chart is a type of graph that represents data in a circular format, with each 'slice' representing a proportion of the whole. It is not typically used to provide an overview of a project.

b. Gantt chart

• A Gantt chart is a type of bar chart that illustrates a project schedule. It shows the start and finish dates of the terminal elements and summary elements of a project. It is commonly used in project management.

c. Line graph

• A line graph is a type of chart which displays information as a series of data points connected by straight line segments. It is not typically used to provide an overview of a project.

d. Dot graph

• A dot graph, or dot plot, is a statistical chart consisting of data points plotted on a fairly simple scale. It is not typically used to provide an overview of a project.

Therefore, the correct answer is b. Gantt chart. A Gantt chart provides a graphical overview of a project, showing the tasks involved, their sequence, duration, and any dependencies between tasks.
