Requesting the Integration of Visualizations on stlouis-mo.gov

Overview

Many of our City Offices, Agencies, and Departments collaborate with external partners, consultants, and citizens to collect data and create visualizations. 

To ensure these visualizations are accessible, secure, and compatible with our systems, all submissions must meet the following guidelines. These requirements help us maintain consistency, usability, and compliance with our accessibility and security standards.

Supported Platforms

We support the integration of visualizations created through:

• ESRI Mapping Products (e.g., ArcGIS Online, ESRI API)
• Tableau (Public or Server-hosted dashboards)
• Other Government Agencies (A CDC visualization, for example)

If you are using another platform, please contact us before submission to assess compatibility.
