On this page I've shared the Network Mapping tool created by a team of Indiana University students in the Fall 2025 Information Visualization (IVMOOC) class.
This week I received the final report from a second IVMOOC team, who used the same Tutor/Mentor Conference history, to visualize participation. Below is the interactive map-based visualization that they created.
Open the interactive map at this link. Across the top of the map are dates of the 1994-2015 Tutor/Mentor Leadership and Networking Conferences, held in Chicago. For each conference the IVMOOC team created a zip code map, with shaded areas showing where conference participants came from.
--- beginning of text from the report ----
Total Participation: Shows the overall number of participants from each ZIP code. This view highlights the most active regions and provides a baseline for geographic engagement.
Change in Participation: Displays year‐to‐year changes in participation by ZIP code. Areas shaded in stronger colors indicate growth, while lighter or negative values highlight declines. This view is useful for spotting emerging regions or places where engagement has tapered off.
New Members: Focuses on participants attending for the first time. This metric helps identify ZIP codes that are contributing fresh engagement and expanding the community base.
Recurring Members: Highlights ZIP codes with participants who attended multiple times.
The total participant count increased gradually from the 1990s through the early 2010s, suggesting a steady growth in engagement. However, the participation rate dropped slightly in the final years, likely due to changes in outreach or available data coverage. (Note - this was largely due to less funding available to host and market the conferences following the 2011 decision of the Board of Directors to discontinue support of the Tutor/Mentor Connection part of the Cabrini Connections nonprofit, that was launched in late 1992. While I formed the Tutor/Mentor Institute, LLC to keep this strategy available to Chicago, I never found significant funding due to no longer operating as a 501-c-3 non profit.)
Geographic concentration: Participation spanned 616 ZIP codes across 45 states, but Illinois dominated with about 66% of all participants. Chicago alone accounted for over 5,500 entries, underscoring its role as the central hub. After 2005, participation gradually expanded into nearby states such as Indiana, Michigan, and Wisconsin, reflecting regional growth. (This also reflected the growing use of the Internet since the early 2000s).
Organizational diversity: More than 1,532 unique organizations were represented. Nonprofit and education-related groups contributed the majority of attendees, while donor and policy-focused organizations made up a smaller share, highlighting a sector imbalance.
Temporal trends: Yearly participation fluctuated, peaking in the late 1990s and early 2000s, followed by a gradual decline after 2010. This suggests that outreach strategies or conference accessibility may have shifted in later years. (As noted above, there were less funds available after 2011. However, there also was growing competition as others hosted their own networking events. And with the Internet, there were fewer reasons for people to attend face-to-face events.)
Our analysis has shown strong participation from nonprofits and educators, but limited involvement from donors and policymakers. This imbalance suggests that the conferences primarily served as spaces for practitioners and community‐based organizations rather than funding institutions. While this helped strengthen grassroots connections, it also limited opportunities for broader institutional influence and resource mobilization.
● Community clusters: The dashboard shows that nonprofit and education‐related ZIP codes consistently appear with high intensity, especially in Illinois. Many of these areas also show strong recurring member counts, reinforcing the persistence of local and regional communities over time. (Note. if you view many of the maps on this blog you'll see where poverty is concentrated in the Chicago region. If there were a demographic overlay to the IVMOOC map it would show most of the participating organizations came from these high poverty areas. That was our goal.)
● Peripheral actors: When switching to the “new members” view, donor and policy‐related ZIP codes appear less frequently and with weaker intensity. Their limited presence suggests missed opportunities to expand engagement beyond practitioner and educator communities.
● Regional hubs: Chicago and surrounding Illinois ZIP codes dominate across all dashboard views, acting as central hubs of participation. After 2005, the dashboard highlights new activity in Indiana, Michigan, and Wisconsin, showing geographic expansion and gradual integration of neighboring states into the conference network.
● Retention vs. outreach: The dropdown comparison between recurring members and new members reveals a balance between retention and outreach. Some ZIP codes show strong recurring participation, indicating long‐term commitment, while others contribute more new members, highlighting successful outreach into fresh regions. Together, these dashboard insights suggest that while the conferences were highly effective at sustaining nonprofit and education networks, future outreach could focus on strengthening donor and policy participation and leveraging regional growth beyond Illinois.
The report reinforces what I recognized since launching the conferences in 1994. We were attracting many of the volunteer-based tutor/mentor programs in the Chicago region, along with some of the university programs and researchers involved in doing this work. Occasionally we had participation from foundations, business, universities and local media. However, we never were able to attract a large and consistent following of business, philanthropy and policy representatives.
