A heat map is a graphical representation of data where the individual values contained in a matrix are represented as colors.

Data visualization in transportation aims to identify trends and patterns, communicate complex data, and make data more accessible to stakeholders.

A choropleth map is a thematic map that uses different colors or shades to represent the values of a quantitative variable across a geographic area.

A Sankey diagram is a flow diagram that represents the flow of traffic between different locations or nodes in a transportation network.

A line chart is a graphical representation of data where the data points are connected by a line, making it suitable for displaying trends and changes over time.

Interactive data visualization tools allow users to explore data in real-time, provide a more engaging user experience, and enable users to customize the visualization according to their needs.

A scatter plot is a graphical representation of data where each data point represents the value of two variables, making it suitable for displaying the relationship between them.

A box plot is a graphical representation of data that shows the median, quartiles, and outliers, making it useful for identifying outliers, comparing distributions, and visualizing the range and variability of data.

A choropleth map is a thematic map that uses different colors or shades to represent the values of a quantitative variable across a geographic area, making it suitable for displaying the spatial distribution of transportation infrastructure.

Dashboards in transportation data visualization provide a comprehensive overview of key metrics, allow users to monitor data in real-time, and enable users to drill down into the data for more detailed analysis.

A bar chart is a graphical representation of data where the height of each bar represents the value of a category, making it suitable for displaying the distribution of traffic accidents by time of day.

A bubble chart is a graphical representation of data where each bubble represents a data point, with the size of the bubble representing the value of a third variable, making it suitable for representing the relationship between three variables, comparing the size of different entities, and visualizing the distribution of data across different categories.

A radar chart is a graphical representation of data where multiple quantitative variables are represented on axes starting from the same point, making it suitable for displaying the performance of different transportation modes in terms of energy efficiency.

A treemap is a graphical representation of hierarchical data where the size of each rectangle represents the value of a category, making it suitable for visualizing hierarchical data, providing a compact representation of data, and enabling users to identify patterns and relationships.

A Sankey diagram is a flow diagram that represents the flow of traffic between different locations or nodes in a transportation network, making it suitable for displaying the origin and destination of traffic flow.
