AMCHARTS Venn Diagrams
Earlier I wrote about trying to make a Venn diagram to show that high school graduates that meet University System of Maryland (USM) requirements and Career Technology Education (CTE) requirements were a subset of all high school graduates. I could not get the Venn diagram to render correctly. Today I figured out the correct syntax. I had to define areas in the Venn diagram that I did not actually want to show. That is, I had to define “USM HS Grads” and “CTE HS Grads” and “Both Requirements Grads” even though I do not want them to render separately in the chart. I know that is not the best explanation, but I want to just quickly make this diagram live to see if how it works on a live webpage. I will revisit this Venn diagram again soon with further refinements.

Remiation Rates of Recent Maryland Public High School Graduates Enrolled at Maryland Public Institutions
Today I take a look at the remediation rates of recent Maryland public high school graduates enrolled at Maryland public institutions as published by the Maryland Higher Education Commission in their 2021 Data Book. According to data published by the Maryland State Department of Education, 57,622 students graduated from Maryland public high schools during the 2017-2018 academic year. According to MHEC’s remediation data set, 25,575 students enrolled at a Maryland public institution in fall 2018. Thus, less than half, 44%, of the public school graduates are reflected in the map below. So, the data may tell us less about the quality of public schools than first thought. I will have to see if I can drill down further to this data. My first step will be to look at the number of high school graduates from each county; however, since the percentage of students who are low-income is different in each county, the college-going behavior is likely not consistent.
I was a little surprised to see that 25,575 students enrolled in a public institution immediately after high school because according to the college pipeline data published by the Maryland Longitudinal Data System Center, 17,410 students enrolled in a public institution immediately after high school. I wonder if MLDS is better able to separate students enrolled in multiple institutions. Further, the MLDS dataset only is capturing “degree-seeking” students.
Notes About the Data
- Students may be enrolled at more than one institution. They are included in enrollment figures for each insituiton at which they are enrolled.
- Data include all degree- and non-degree seeking students enrolled in credit courses.
- Maryland residents are identified using their place of residence at the time of application to the insituion.
- Maryland public instiutitions include community colleges and four-year public colleges and universities.
- Recent Maryland public high school graduates are defined as those graduating from a Maryland public high school, identitifed using the College Board School Code, who graduated in the 2017-2018 academic year and first enrolled in higher education in Maryland in fall 2018. Analysis relies on high school graduation date and reporting of remedial assesment data; missing data for these variable may result in underreporting.
- Maryland residents whose county of residence is unknown are included in insitutuional-level remedial data, but excluded from reporting by county of residence.
- Salisbury University and St. Mary's College of Maryland do not offer remedial coursework.
Venn Diagram in AMCHARTS
This post is mainly to show that I learned how to code a Venn diagram in Amcharts. However, I still have a ton to learn about how to code the data and what the data means. The Venn diagram is not one of the preset charts available in the Amcharts WordPress plugin. That said, with a little trial and error I was able to copy one of their examples and make it work. The main challenge was figuring out the correct resources to load.
I got data from the Maryland State Department of Education about high school completion for the class of 2019. It shows the number and percentage of students that left high school with a variety of qualifications. Three of the categories are University System of Maryland (USM) requirements, career technology education (CTE) requirements, and the requirements for both. Generally, the USM requirements are completing the credits required for admittance to a USM institution.
To be a CTE completer, a student must complete an approved CTE course of study. CTE programs are typically about 4 credits.
Since MSDE publishes the number of students in the State that complete both the USM and CTE requirements I can build a Venn diagram. The data below is for the entire State of Maryland. It is the first Venn diagram I have built using Amcharts. I need to explore more of the options. However, since it is easy for me to break the functionality of the charts using Amcharts, I will explore the functionality slowly and iteratively.

As I figure out the program you need to click on the actual post or this link to see the chart. I am working on this issue.
Future Venn Diagrams
It is sad that I probably will not be able to create a completely accurate Venn diagram for all of the high school completer options because I do not know how the categories overlap, but I will probably play with trying to set up a "representation" with a bunch of stated assumptions.
Update: Technical Issues
As I learn about these computer programs I am bound to run into technical issues because I am coming at this data from a public policy and scientific background. My last formal coding training was in 1992 or so when I was in middle school. As I was making these charts I ran into the (documented) issue of needing to use a specified placeholder value for the charts so that they show up properly. I failed to do that for a few charts because I was copying pieces of code from other places. I think I figured out that issue after a bit of trial and error. Now I've run into the problem of a few of the Amcharts not properly rendering when as part of the blog stream, but will render as part of an individual post. I have made a workaround of explaining the issue and posting a link to the post, but I am going to continue to explore a more elegant solution. The issue is probably I am missing a piece of code.
