Concept
The concept / theme for this data visualization is the comparison of parking an electric car and parking as an invalid.
First a call was started with the support group to create a mind map. The intention is to see new insights that can lead to a concept. In the mind map of my support group we looked at different perspectives for the theme 'Cars in the city', such as accessibility, environmental pollution, parking rates. This mind map is shown below:
First I came up with the idea to visualize the main question below: What does the parking option for electric cars in public parking facilities in the Netherlands look like?
The problem with this main question is that it is a fairly complex main question. Based on the feedback I received from @razpudding, I decided to formulate my question slightly differently. I also made my research question more interesting by involving accessibility. My main question now is:
I think there are more electric charging points available than there are disabled parking spaces.
For the main question I came up with a number of sub questions:
-
What is the ratio of parking spaces for electric cars / disabled parking spaces in the Netherlands?
My assumption is that there are fewer parking spaces available for the disabled than for electric cars. So I think the ratio is 1/3. -
Where are parking facilities for disabled people in the Netherlands?
My assumption is that there are more parking facilities for disabled people in the big cities. -
Where are parking facilities for electric cars in the Netherlands?
My assumption is that there are fewer parking facilities for electric cars in the big cities.
To make a visualization, I will use the RDW datasets:
The variables I need:
- AreaId
- DisabledAccess
- ChargingPointCapacity
- Location
- AreaDesc
Before creating the visualization using the code, it is important to consider how I want to create my visualization. For this reason, various sketches have been made. I have shown these below:
