Please see the data notes from the elementary cases post.
I am aware that George Fox Middle School has been renamed Northeastern Middle School, but I am not sure how to change the name in the shapefile. I will need to figure it out in the future. Schools without a physical district are not included.
This map should be taken with a grain of salt. It is primarily a learning activity for me.
Total cases represents active student and teacher/staff cases as of September 14, 2021.
These notes are taken from the Anne Arundel County Public Schools data dashboard.
1. The tables on this page reflect positive cases, confirmed by testing, with an onset date of September 8, 2021, or later that have been made known to Anne Arundel County Public Schools. Schools/Offices with zero student or staff cases do not appear in the tables. The data also includes cases of COVID-like symptoms in which a person is not tested for a period of 48 hours after onset of symptoms, and probable cases, which occur when an individual with a COVID-like symptoms is found to have close contact with someone who is COVID-19 positive. Such cases are treated as if they are positive for COVID-19 in terms of identification of close contacts and potential exposures. Cases that appear on this dashboard and are later determined to be false positives or the like will be deleted in subsequent updates.
2. An “active case” is one in which the individual who tested positive is still under 10-day quarantine.
3. A positive case, COVID-like symptoms case, or probable case does not mean the individual exposed others at school or work, or that the individual contracted the virus at school or work.
4. Students enrolled in virtual-only learning and who are not part of any extracurricular activities are not included in this data.
5. Due to differences in reporting methodology, this information may not match the data presented by the Maryland Department of Health.
This is my Anne Arundel County map trial in amcharts. The
This is how I fixed my Anne Arundel County map after going back to my notes and fixing the CSS just like I did for my Maryland map. This is why I document everything I do. If I do not document my process I will forget.
Anne Arundel County County Public Schools published data today regarding COVID cases in public schools. Their reporting metrics are different than those reported by the State. I decided to map and publish it. I have not yet checked the data. I need to publish the data to check it.
After playing with the map a bit I decided that the dots were rather overwhelming, so I shrunk them to their smallest possible size. The dots size for the other maps was the default size. I will need to remember to consider dot size in the future.

The Anne Arundel County Public Schools data will be updated each Wednesday.
I learned how to create a map with only Anne Arundel County, which required me to find a JSON geofile of Anne Arundel County and convert it to the correct file format. It works, I hope I’m allowed to use the files I used to make the base map. I think I will be able to add other Anne Arundel County open data to the map in the future. I added the Anne Arundel County school-associated cases to the map to see if it rendered correctly. It does.
I’m not sure why the bottom of the map is cut off. I will have to explore that issue next.
Out of curiosity, I updated the school outbreak-associated cases map to reflect the data as reported by the Maryland Health Department on September 15, 2021.
After my experiment using smaller dot sizes, I updated this map to also have the smallest dot sizes. I think it is easier to read.
These charts shows the student level: freshman, sophomore, junior, senior, or unclassified of students that transfer from Maryland community colleges to University System of Maryland institutions. According to the notes on the data by the University System of Maryland, the transfers are the number of undergraduates enrolled for the first time at the institution with known prior undergraduate post-secondary experience. The students may or may not have transferred credit.

I found code for a drill-down sunburst chart on Amchart’s website. I just popped in the data I had already typed up that has Bowie State Univesity spring 2021 headcount enrollment by area of origin. This version is kind of nice because you can drill down to see the details of the smaller categories. A disadvantage is that you can not see the drill-down categories until you drill down. In the future, I may be able to figure out how to show the hidden layers, but I am not sure if that will be an advantage, it might be too close together to see the categories well.
To drill down to a level click on the pie slice. This will expand the slice to the entire area of the pie. It is rather difficult to explain, it is easier to just play with the chart down below to understand how it operates.
The drill-down sunburst chart goes down to the level provided in the original data. For in-State students, the data shows to the county level the area of origin. For out-of-state students, it shows students from the major surrounding states and the District of Columbia. The states are New Jersey, New York, Pennsylvania, and Virginia. The remaining students are from other states, “foreign”, or of unknown origin.
To make the other sunburst chart look cleaner I divided the counties into five regions: Capital Region, Central Maryland, Southern Maryland, Western Maryland, and Eastern Shore. The regions and the counties assigned to each region are from the “Visit Maryland” website. For this semester Bowie State University had no students from Western Maryland counties, so that region is not on the chart. As with the other charts, I withhold judgment on the chart until I have an opportunity to play with it.

Since I was able to get the sunburst chart to finally work properly. I decided to take a look at the data I entered. For some reason, the enrollment for winter 2021 is really low (COVID and short term?), so I decided to pull numbers of a more typical term (still COVID) to get a better idea of actual enrollment. I wrote the code in a text file, so I have not yet taken a look at the chart. However, I know from just looking at the data that Prince George’s County has the highest headcount enrollment. This is logical because Bowie State University is located in Prince George’s County.

In my last post, I said that I could not get the Sunburst Chart to render properly out of CodePen. I walked away with plans to go to bed. Getting ready for bed I did a few minutes of googling and found a Reddit post from three years ago that explained my issue. Apparently, since it was running locally I need to add “https:” prior to the resources in the HTML part of the code.
Below I have quoted partly how it was explained on the Reddit post. Basically, without the https:, which is sometimes assumed and can be assumed when it is running off CodePen, the computer does not know what it looking at. Thus, my code will not render. Since I am new to this and kind of just trying to make things work, I will be adding in the “https:”

…when you don’t use an explicit scheme, then your brower will use the scheme of your page. … This is also why this gave you problems when running locally: if your page is served under file:///some/path/to/your/file.htlm then the url// mascdn.bootstraphcdn.com/font-awesome/4/2.0/css/font-awesome.min.css resolves to file://maxcdn.bootstrapcdn.com/fount-awesome/4.2.0/css/font-awesome.min.css, which doesn’t exist. …
When I was running the code without the “https:”, it would just spin its wheels. There was no error code.

I need to type in all my data before I can decide if I like a chart. The Sunburst chart is kind of interesting, it allows for drilling down of data, which I really like. The issue with the particular chart is that there is so much data the chart is kind of difficult to read. In my first version, I did not have the in-State enrollment divided by region and it was even harder to read.
