Topics in Data Visualization using Statistical Graphs

1

Graphs and Axes

  • A graph is a pictorial representation or a diagram that represents data or values in an organized manner.
  • Graphs show the relationship between two or more things using points, lines, or curves.
  • Graphs have two axes: the horizontal X-axis and the vertical Y-axis.
2

Types of Graphs

  • Bar graphs present categorical data using rectangular bars.
  • The height or length of each bar is proportional to the value it represents.
  • Bars in a bar chart can be vertical or horizontal.
3

Dimensionality of Data

  • Dimensionality is the number of columns of data, which are the attributes of the data.
  • A dataset with n observations and m columns is m-dimensional.
  • The number of dimensions can change without forcing a change in another dimension.
4

Dimensionality Reduction Techniques and High-Dimensional Visualizations

  • Principal Component Analysis reduces the dimensionality of data by finding principal components that capture the most variance.
  • PCA can reduce data for visualizing it in 2D or 3D.
  • t-SNE is a non-linear dimensionality reduction technique.
