What Day of the Week We Have More Crashes?*

For this type of data, you're looking at categorical variables (days of the week) against a quantitative measure (number of crashes).

Bar Plot: Simple and effective way to visualize the frequency of crashes by day of the week. Each bar is a day of the week, and the height of the bar is the number of crashes.

Heatmap: If you have data over multiple weeks or want to show variation in crash frequency by day over a period of time, a heatmap might work better. Days of the week would be on one axis, and weeks (or another time division) on the other, with colors representing crash frequencies.

Crashes/Injuries Across Different Months in a Map Plot

To visualize crashes and injuries across different months on a map, especially if you want to show changes over time or compare between crashes and injuries geographically, consider:

Choropleth Map: Useful for showing how crash or injury counts vary across different regions or states. You can use different colors to represent different ranges of counts. For temporal changes, consider creating a series of maps for each month or use an interactive slider to change the month being viewed.

Bubble Map: Overlay bubbles on a geographical map, where the size and color of each bubble represent the number of crashes or injuries. This type of map can effectively show the geographic distribution and magnitude of crashes or injuries. You can create separate maps for each month or use interactivity to switch between months.

Having Both Number of Crashes and Number of Injuries Statistics

When you have two related quantitative measures for each category (e.g., crashes and injuries by day or month), you might want to show these relationships or compare them directly. Here are some ways:

Stacked Bar Plot or Grouped Bar Plot: For comparing crashes and injuries side by side for each category (e.g., day of the week or month). Stacked bars can show the total of crashes and injuries combined, while grouped bars can facilitate direct comparison between the two.

Dual-Axis Chart: Use a bar plot for one measure (e.g., crashes) and a line plot for the other (injuries) on a dual-axis chart. This can help in visualizing the relationship between crashes and injuries over time or by category.

Scatter Plot with Faceting: If you're interested in exploring the relationship between crashes and injuries, a scatter plot can be useful, with each point representing a day or month. You can use faceting to create separate scatter plots for each month or day of the week to see how the relationship varies over time or by category.
