ActivityViz is an interactive travel and activity data visualization tool. It is built with JavaScript technologies and works with various types of travel and activity data - household travel surveys, trip-based model outputs, activity-based model outputs, disaggregate passive data, freight models, on-board surveys, etc.
The dashboard features several interactive and customizable visualizations for exploring data, such as 3D maps of trips in time and space, time use by person type and activity, radar charts for performance measure analysis, sunburst diagrams for visualizing mode shares, animated bubble maps, chord diagrams for OD data, point-of-interest maps for transit stop data, truck flow data, etc. ActivityViz is published using GitHub pages which eliminates most of the administrative backend in traditional systems. This improved deployment strategy makes maintenance much easier for data science users.
ActivityViz was initially funded by the Atlanta Regional Commission (ARC), with additional support from Oregon Metro and others.
- The master branch is the release / stable version, the develop branch is for development, and gh-pages is the current published demo
- To make contributions, fork the repo, make revisions, and issue a pull request to develop.
- Once contributions are acceptable, then we will merge develop to master and then master to gh-pages
ActivityViz supports configuration for multiple regions. To setup ActivityViz in your region:
- Fork this repository to your GitHub account
- Edit
config.json
for the desired region and data locations - Data locations can be stored local to the repository or online
- Examples for a region named "rsginc":
- Local:
"datalocation": "/data/rsginc/"
- Via GitHub:
"datalocation": "https://github.com/raw/RSGInc/ActivityViz_data/master/data/rsginc/"
- Local:
- Examples for a region named "rsginc":
- The first region will determine which graphics are shown on the main page.
- Copy an existing region.json file into the region folder.
Each region supports data for multiple scenarios. Do the following to add scenario data:
- Create a new folder in the region specific folder with the scenario name
- Copy in the data tables that supply the data for the visualizations, each with the following set of fields:
- BarChartAndMapData.csv: ZONE, COUNTY, <BAR_LABEL>, QUANTITY
- 3DAnimatedMapData.csv: ZONE, PERIOD, QUANTITY
- TreeMapData.csv: GROUP1, GROUP2, GROUP3, ..., QUANTITY
- RadarChartsData.csv: AXIS, CHART, <QUANTITY_1_LABEL>, <QUANTITY_2_LABEL>, ...
- BarChartData.csv: BARGROUP, COLUMNS, QUANTITY, CHART
- ChordData.csv: FROM, TO, <QUANTITY_1_LABEL>, <QUANTITY_2_LABEL>, ...
- Scatter.csv: LABEL, XAXIS, YAXIS, SIZE (YAXIS/XAXIS)
- PointofInterest.csv: POINTS OF INTEREST, FILTER, LAT, LNG, GROUPING, <QUANTY_1_LABEL>, <QUANTY_2_LABEL>, ...
- TimeUseData.csv: GROUP, TIME PERIOD, PURPOSE, QUANTITY
- HeroImageLayout
- If truthy, display landing page with a hero image instead of with the default "list of links" layout.
- HeroImage
- If HeroImageLayout is true, this value is the
src
of the background hero image.
- If HeroImageLayout is true, this value is the
Notes:
- All data tables are not required and each data table is used to populate a specific visual. Take a look at the example data tables to see how each visual is constructed based on the data. Most of the visuals are populated based by what is in the data tables, thereby making the visuals highly customizable.
- Avoid special characters such as space, slash, etc. in table data (column names and data entries).
- TimeUse: The PERIOD entries for TimeUse and 3DAnimatedMap are 1 to 48 and represent 30 minute periods from 3am to 3am the next day. The TimeUse purposes must be ALLCAPS and must include at least HOME, WORK, SCHOOL. TimeUse must also include an ALL person types.
Each Data/Region folder needs the following:
- Title: Title that shows up in tab of web page
- CountyFile: Name of the geojson file with region counties
- ZoneFile: Name of the geojson file with zones and property id for zone ids
- Icon: ico format agency logo image file stored in the img folder (use an online converter from png if needed)
- Logo: png format agency logo image file stored in the img folder (use an online converter from png if needed)
- NavbarTitle: Name to appear in the navbar
- LinkURL: URL of the link that appears in navbar
- CenterMap: Lat/Lng in decimal degree of the center point for the maps to use

- SideBarTextRight: Right bottom text box on web page
- SideBarLogo: Web page top image to the right (omit if desired)
- SideBarImage: Web page bottom image to the right
- DefaultFocusColor: Sets the default color to use for the focused GeoJSON object if included on a map
- DefaultHighlightColor: Sets the default color to use for highlighting filtered zones if included on a map
- scenarios: Defines each scenario. Each scenario is an object, the name of the scenario is the name of the object.
- title: the sub text or title of the scenario that will appear along with the name on the front page
- CenterMap: overrides the region specific center of map, will also focus in on the point rather than find best view
- label: overrides the default scenario - title setup for the scenario and instead displays the label text in all cases
- ScenarioFocus: filename of GeoJSON to be displayed on the maps (BarChart with Map, Point of Interest and Chord Map)
- visualizations: set of visuals to be display on the scenario specific page, the order they are defined will determine the order of the tab
- visuals are Sunburst, 3DMap, GroupedCharts (standard barcharts), TimeUse, RadarCharts, BarMap (barchart with map), Chord, and POIMap (barchart with POIs instead of zones)
- Each visual title allows for an array of multiple charts. Each entry will be it's own tab on the scenario specific page.
- Each chart object requires a "name", "config" (name of configuration set to use) and a "file" (filename that will contain the data).
explanation
Optional - JSON object which configures an explanatory panel to the left of the visual (see Visualization Explanations below).- Optional chart properties: "info" - is is a tooltip to appear next to the chart title, "datafilecolumns" - a key/value object that will display underneath the data table on the bottom of the chart tab
- Example of multiple visuals for single chart type: "GroupedCharts": [{"name":"GroupedCharts","config":"Default", "file":"BarChartData.csv"},{"name":"GroupedCharts2","config":"Default", "file":"BarChartData2.csv"}],
Each chart type has a different entry for their specific configuration settings. You can set up several different configuration entries for each chart type. This lets you customize the each chart tab. The property entry is the name of the configuration, each chart needs to have at a minimum an empty (example: "BarMap": { "Default": {} } ) configuration.

Custom configuration is not available for the chart type level for time use charts, but each chart
object under the visualizations
array can be given a title
property to replace the words "TIME USE" in the page header.

: If this is true, then the toggle between "Counts" and "Percentages" will be hidden.DisplayCountsByDefault
: If this is true, the default TimeUse chart display will show the counts, not the percentages.
Scenario data folder with its name equal to its scenario entry, can either be local or in the cloud. Location of the region's scenario data folder is specified in the main config.json file
Zone polygons with the id property equal to the zone number. Polygons also require the NAME property to display desire lines and link up with data sets. The open source mapshaper will convert and simplify a shapefile to geojson. 4. Counties.geojson - County polygons with the Name property equal to the county name.
Each visualization
object supports an explanations
property. This property is a list of Explanation
objects.
Property | Type |
---|---|
header |
string |
body |
ContentSection[] |
The header
property populates a header at the top of the explanation. The body
property is the contents of the explanation - it is a list of ContentSection
s
Property | Type |
---|---|
type |
string (enum) |
content |
string[] |
The type
property may be one of the following:
"paragraph"
- creates a list of paragraphs of the strings in content"orderedList"
- creates a numbered list of the strings incontent
"unorderedList"
- creates a bulleted list of the strings in `content
Example of how this would look in the demo RSG BarMap visualization:
{
"BarMap": [
{
"name": "Daily Truck Trips",
"file": "BarChartAndMapData.csv",
"config": "Default",
"info": "Truck trips by zone and county",
"explanation": [
{
"header": "Explanation",
"body": [
{
"type": "orderedList",
"content": ["one li", "two li", "red li", "blue li"]
},
{
"type": "unorderedList",
"content": ["one li", "two li", "red li", "blue li"]
},
{
"type": "paragraph",
"content": ["one p", "two p", "red p", "blue p"]
}
]
}
]
}
]
