OSS Census Visualizations

Customize Visualizations

Highcharts graph JavaScript can be found in js/visualizations/ for each graph. You can modify the JS to customize each graph.

All Highchart Imports are linked at the top of each HTML file.

In each JS file, you'll see that a JS object obj is accessed like the following:

obj.title

That variable is set based on our functions in parse.js. The variable's attributes must be updated to different fields in data.js based on the graph.

var obj = data["Commit"]["All"]

The data variable is located in js/data.js. This JS file's data is shared by <script> tags in our .html files. data stores information in JSON format (like a Python dictionary), where nested fields store array data for each graphs.

To see how we modify data stored in this variable, read in the next section "Update Data" and check out js/data.js file.

Update Data

census_interactive/data/raw stores CSV data uploaded from our server. Feel free to update these CSV files if there is more update-to-date data.

census_interactive/data/processed stores JSON data of each graph's CSV. It's formatted into specific fields via scripts from process.py and these fields are accessed in each graph's script.js file.

census_interactive/process.py module contains functions named load_CATEGORY to format data from data/raw. Using this data, each function creates the appropriate axis labels, a dictionary or array (used for plotting line graphs) that are stored as JSON in data/processed. Run the run.py script after updating any of these functions to compile new data into data.js. Each chart's JS files access variables from data.js.

  1. Ensure proper setup by ensuring all imports are installed
python -m pip install -r requirements.txt
  1. Specify languages and single graph comparison options in config.yaml
  2. Execute run.py script
python run.py

Executing the run.py script invokes calls to the process.py functions for specified graphs in config.yaml, formatting the data into nested fields (dictionary format) per language, per graph type. The script finally updates the data variable in js/data.js with an aggregation of all the JSON files in data/processed, .

Update HTML

index.html home page with links to jump to site pages and external sites

quick_facts.html contains interactive visualizations with brief descriptions

comparison.html able to display multiple stacked bar charts with plot line as well as stack area and polar charts. Heavy JS support and also contains short description on graphs' data source.

references.html annotated bibliography with table of references

footer.html and nav.html shared across HTML files and called with JQuery.

Everything Else

css/ contains style code used in HTML pages. default.css is used for index.html (home) and subpage.css used for remaining pages.

.html pages can be tested locally best via localhost through Python command

python -m http.server

js/*.js defines various files to handle onclick and onchange event functions for updating, adding, and deleting data. Logic for handling changes in user input are also implemented here. Variable data is stored via localStorage.

js/parse.js defines the JSON storage structure and a function to access each graph's data given a category and language.

js/single_graphs.js and js/comparison_graphs.js call JS functions defined in js/visualizations/GRAPHNAME.js to parse each chart data and generate chart. comparison_graphs.js also contains handlers to display multiple graphs on comparison page.

config.yaml lists all data that would like to be processed. If only specific ecosystem's (or "language's") CSV files are updated for example, we may not want to wait for everything to update. The following are the maximum options that can be applied:
