In astronomy, the Hertzsprung–Russell diagram, also known as the H-R diagram, is used to determine and illustrate different star life cycles, based on their luminosity and temperature. This helps astronomers classify stars into different spectral types. The Hertzsprung-Russell Diagram is an invaluable source when studying the universe.
Traditional H-R Diagram
Diagrams, such as the H-R Diagram, can be useful in every field to better help the reader understand the data being presented before them. To illustrate the idea that diagrams like the H-R Diagram can be used on any topic, the Silas Babilonia Diagram was created. This diagram was based on data on findings of household income, presented in an article by Pew research. This data showed the median household income by the race/ethnicity of the householder, illustrated in the graph below.
The SB Diagram
The disparities between the races are apparent and vastly different. It appears by no coincidence that the races in america are not quite fully equal, with the reasoning behind these inequalities being left for speculation. Asians are the wealthiest, followed by whites, and hispanics and blacks are tied for third place. This image shows that the population of America is varied in income, with no race being completely equal.
While the H-R Diagram and the SB Diagrams might not be similar in content, they both show how data can be transformed into a more visually appealing format in order to get a point across. Both populations follow a set pattern and contain a wide spectrum of data accumulated over time. It’s important to realize the importance of these diagrams to better understand their usefulness.
