Accelerographs record the acceleration of the ground with respect to time.
The heart of the knowledge graph is a knowledge model: a collection of interlinked descriptions of concepts, entities, relationships and events.
- Descriptions have formal semantics that allow both people and computers to process them in an efficient and unambiguous manner;
- Descriptions contribute to one another, forming a network, where each entity represents part of the description of the entities related to it;
- Diverse data is connected and described by semantic metadata according to the knowledge model.
Graphs and Charts
Every type of graph is a visual representation of data on diagram plots (ex. bar, pie, line chart) that show different types of graph trends and relationships between variables. Although it is hard to tell what are all the types of graphs, this page consists all of the common types of statistical graphs and charts (and their meanings) widely used in any science.
A line chart graphically displays data that changes continuously over time. Each line graph consists of points that connect data to show a trend (continuous change). Line graphs have an x-axis and a y-axis. In the most cases, time is distributed on the horizontal axis.
- When you want to show trends. For example, how house prices have increased over time.
- When you want to make predictions based on a data history over time.
- When comparing two or more different variables, situations, and information over a given period of time.
Digital Customer Experience
Bar charts represent categorical data with rectangular bars (to understand what is categorical data see categorical data examples). Bar graphs are among the most popular types of graphs and charts in economics, statistics, marketing, and visualization in digital customer experience. They are commonly used to compare several categories of data.
AEach rectangular bar has length and height proportional to the values that they represent. One axis of the bar chart presents the categories being compared. The other axis shows a measured value.
- When you want to display data that are grouped into nominal or ordinal categories (see nominal vs ordinal data).
- To compare data among different categories.
- Bar charts can also show large data changes over time.
- Bar charts are ideal for visualizing the distribution of data when we have more than three categories.

Another important feature of RDF databases is their inference capability where new knowledgecreated from already existing facts. can be created from already existing facts.
Graph of the heart
However, the real power of knowledge graphs comes when we transform our own data into RDF triples and then connect our proprietary knowledge to open global knowledge.
