Directed graph (or Digraph): A graph in which edges have a direction, indicating a one-way connection from one vertex to another. Undirected graph: A graph in which edges have no direction, and the connections between vertices are bidirectional. Weighted graph: A graph in which each edge is...
A histogram is a graph counting how many pixels are at each level between black and white.Black is on the left. White is on the right.The height of the graph at each point depends on how many pixels are that bright.Lighter images move the graph to the right. Darker ones move it to...

Histograms are similar to bar charts; they are a way to display counts of data. A bar graph charts actual counts against categories; The height of the bar indicates the number of items in that category. A histogram displays the same categorical variables in “bins”. A bin shows how many...
For this example, we will pass the number of bins we would like. This number is context-specific based on what you are trying to show in your graph. hist(home_data$price, breaks = 100) Powered By Histogram of home prices with bin width changed. Image by Author. ...
