https://openassistant-doc.vercel.appDeveloper documentation for OpenAssistant, featuring a React chat component (@openassistant/ui) and a suite of tool plugins including DuckDB, GeoDa, OpenStreetMap, Kepler.gl, and ECharts for data visualization and spatial analysis.
The OpenStreetMap tools for OpenAssistant provide a suite of capabilities to interact with OSM-related APIs for geographic data processing and analysis. Available tools include:
geocoding: Converts addresses to latitude/longitude via Nominatim.routing: Calculates routes between two points via Mapbox Directions API.isochrone: Generates polygons showing reachable areas within time/distance limits.roads: Fetches road networks based on boundary and road type via Overpass API.queryUSZipcodes: Queries US zipcodes within specific map bounds.getUsStateGeojson: Retrieves GeoJSON data for US states.getUsCountyGeojson: Retrieves GeoJSON data for US counties.getUsZipcodeGeojson: Retrieves GeoJSON data for US zipcodes.The OpenAssistant map tools provide three primary capabilities for creating and managing geospatial visualizations via AI function calling:
keplergl: Creates interactive maps with support for point, line, arc, and GeoJSON visualizations, including color styling and data classification.leaflet: Creates lightweight maps from GeoJSON data with customizable styling.downloadMapData: Downloads map data (GeoJSON or CSV) from URLs for use with other mapping tools.The OpenStreetMap tools for OpenAssistant provide a suite of geospatial capabilities to invoke OSM-related APIs. Available tools include:
geocoding: Converts addresses into geographic coordinates (latitude and longitude) via Nominatim.routing: Calculates routes between two points using Mapbox's Directions API.isochrone: Generates polygons showing reachable areas within a specific time or distance limit.roads: Fetches road networks based on boundary and road type using the OSM Overpass API.queryUSZipcodes: Queries US zipcodes within given map bounds.getUsStateGeojson: Retrieves GeoJSON data for one or more US states.getUsCountyGeojson: Retrieves GeoJSON data for one or more US counties.getUsZipcodeGeojson: Retrieves GeoJSON data for one or more US zipcodes.OpenAssistant provides a suite of visualization tools that allow an AI assistant to create plots from datasets using Vega-Lite and Apache ECharts. Available tools include:
vegaLitePlot: General purpose Vega-Lite plots (bar, line, scatter, etc.).histogram: Histogram plots.scatterplot: Scatter plots.parallelCoordinates: Parallel coordinates plots.boxplot: Box plots.bubblechart: Bubble charts.GoogleAIAssistant class is a Google Gemini Assistant LLM implementation designed for client-side use. It extends the VercelAiClient class, inheriting its core messaging and processing capabilities.OpenAssistant provides a set of tools to enable LLMs to create interactive map visualizations. The available tools include:
keplergl: For high-performance interactive maps supporting points, lines, arcs, and GeoJSON with advanced styling and classification.leaflet: For lightweight maps based on GeoJSON data with customizable styling.downloadMapData: For fetching map data (GeoJSON or CSV) from URLs to be used by other mapping tools.OpenAssistant provides a suite of specialized tool packages for AI applications to perform complex computations and visualizations that LLMs cannot natively handle. The available tool categories include:
@openassistant/plots): Vega-Lite (all plot types) and eCharts (box plots, bubble charts, histograms, parallel coordinates, scatter plots with regression).@openassistant/osm): Geocoding (OSM API), Routing and Isochrones (Mapbox API), and U.S. geographic boundary retrieval.@openassistant/map): Interactive visualizations via Kepler.gl and web mapping via Leaflet.@openassistant/duckdb): In-browser DuckDB SQL for local data querying and table operations (merge, filter, sort, group by, aggregate).@openassistant/geoda): Data classification, standardization, spatial operations (buffer, centroid, dissolve), spatial joins, spatial weights, global/local spatial analysis (Moran's I, Geary's C, LISA), and spatial regression (OLS, spatial lag, spatial error model).GridAdditionalData object is used within GeoDa spatial operations (defined in packages/tools/geoda/src/spatial_ops/grid.ts). It contains metadata about a grid dataset, including optional dataset naming and geographic bounding box coordinates.type GridAdditionalData = {
datasetName?: string;
mapBounds?:
{
northwest: { latitude: number; longitude: number };
southeast: { latitude: number; longitude: number };
};
[outputDatasetName: string]: unknown;
};
