heatmap.js is a JavaScript library that can be used to generate web heatmaps with the html5canvas element based on your data. Heatmap instances contain a store in order to colorize the heatmap based on relative data, which means if you're adding only a single datapoint to the store it will be displayed as the hottest(red) spot, then adding another point with a higher count, it will dynamically recalculate. The heatmaps are fully customizable - you're welcome to choose your own color gradient, change its opacity, datapoint radius and many more. The library is dual-licensed under the MIT and the Beerware license, feel free to use it in your projects.

Risk Terrain Modeling, or RTM, is an approach to spatial risk analysis that utilizes a geographic information system to attribute qualities of the real world to places on a digitized map. It operationalizes the spatial influence of risk factors to common geographic units, then combines separate layers to produce “risk terrain” maps showing the presence, absence, or intensity of all risk factors at every location throughout the landscape. Theoretically- and empirically-grounded risk terrain maps show where conditions are conducive for crimes or other hazardous events to occur in the future. RTM offers a statistically valid way to articulate and communicate criminogenic and vulnerable areas at the micro-level.
