A bar graph uses rectangular bars of different lengths to show and compare data.
The lengths of the bars are proportional （成比例的）to the values they represent.
The bars can be vertical, up and down, or horizontal.
柱状图（条形图）使用不同长度的矩形柱来显示和比较数据。
条的长度与它们所代表的值成比例。
条形图可以是垂直的，向上和向下的，也可以是水平的。
A circle graph, often called a pie graph, is shaped like a circle.
It is divided into segments （片段 分段）that look like pieces of a pie.
Percentages are used to compare the segments, which are ordered from biggest to smallest.
圆形图，通常称为饼状图，形状像圆。
它被分成看起来像馅饼片的部分。
百分比用于比较按从大到小排序的段。
Line graphs are used to show the relationship between two variables（变量）, such as time and distance.
These variables are plotted（绘图） on 2 axes, the X-axis and the Y-axis.（axe斧头，axi轴线，坐标轴，axes是以上两个的复数形式）
The x-axis often shows time while the y-axis shows how quantities, such as distance, temperature or profits change with time.
线形图用于显示两个变量之间的关系，如时间和距离。
这些变量画在两个轴上，x轴和y轴。
x轴通常表示时间，而y轴表示距离、温度或利润等数量如何随时间变化。
A flowchart is a type of graph that shows how a process or project flows from start to finish.
A flowchart consists of start points, inputs, outputs and decision points.
流程图是一种显示流程或项目如何从头到尾流动的图。
流程图由起点、输入、输出和决策点组成。
An organizational chart, or org chart shows the structure（结构，组织） of a company.
It shows how people and departments within a company are connected.
It defines the roles and responsibilities of people and departments within a company.
组织结构图显示了公司的结构。
它显示了公司内部人员和部门之间的联系。
它定义了公司内人员和部门的角色和职责。
Line graphs are very good at showing how things change over time.
In a flowchart, a decision point shows that happens when a decision is made.
线形图非常善于显示事物随时间的变化。
在流程图中，决策点表示在做出决策时发生的情况。
