【题目】Paragraph 1: T h e periodic tabl e is a chart that reflects th e periodic recurrenc e of chemical and phys ical properties of th e elements when th e elements are arranged in order of increasing atomic number (the number of protons in th e nucleus). It is a monumen tal ...
In this mode the values of nodes are not taken into account, so the value data field is not required. The elements at the last level of the hierarchy (leaves), divide the circle into equal parts, and the size of each parent element depends on the number of its children. ...
The melting point is the temperature at which the vapour pressure of the solid and the liquid are the same and the presssure totals one atmosphere.Image showing periodicity of the chemical elements for melting point in a bar chart.Units
A word tree is a visualization that displays text data in a hierarchical way: as a tree of elements, usually single words, connected by lines. The font size of words represents their weight - the frequency / number of children. This type can be used to show typical contexts a root word...
There are used many types of diagrams, each of them has its own fields of application. Flow diagram is a diagram that illustrates the flow or set of dynamic relationships in a system, visually depicts the structure of the elements in a complex system and their interactions. The term Flow ...
