The aim of this exercise is to pick an existing visualization improvise it using best practices of visualization.
This visualization looks into crime in Vancouver over the past 8 years. Reference tableau public project (original Tableau Project):
Observations : This dashboard organisation of this visualization is good.And also looking at the data set used, the chart types used are good. But there were a few changes that can make the dashboard even better. The following is my attempt at redesigning the dashboard:
Modified Visualization link : https://public.tableausoftware.com/profile/pratish#!/vizhome/DataViz_Redesign_CrimeVancouver/CrimeinVancouver
Changes to the dashboard.
- Diverging color to Sequential color: For ranges which are not diverging in nature its not a good practice to put such a palette. A sequential palette can be associated with an increase in value of range.
- Axis Label Orientation: The chart type depicting total crime of a particular type has its X axis text oriented in a way difficult to read.
- A chart showing the year-wise comparison of the number of crimes in Vancouver. This is an interesting observation, the total number of crimes has been falling steadily over the years.
- Neighborhood crime data: This data when set descending, is easier to see the higher crime areas.
- Changes in font and color to be consistent. And to give a better visual feel.
