feat: Add deck.gl Heatmap Visualization #23551

Mattc1221 · 2023-04-02T02:52:22Z

SUMMARY

Adds the heatmap layer from deck.gl here.

Related SIP: #23553

Rationale:

Superset already has supported functionality for other deck.gl visualization layers (e.g. Arc, Geojson, Grid, Hex, Path, Polygon, Scatter, Screengrid). Since Superset already contains the logic to handle deck.gl layers, it is straightforward and easy to maintain to add new deck.gl layers.

By expanding the range of available deck.gl visualization layers, users will have more options to choose from when creating their visualizations. This will allow them to tailor their visualizations to their specific needs and explore their data in different ways. It will also allow Superset to better compete with other data visualization tools on the market that offer a wider range of visualization options.

Overall, I think adding more deck.gl layers to Superset is a great idea and has the potential to significantly improve the user experience and the insights that users can gain from their data.

Design Decisions

The addition of the Heatmap layer follows the structure of existing deck.gl layers to maintain readability and consistency within the codebase.

Structure:
The directory superset-frontend/plugins/legacy-preset-chart-deckgl/src/layers/Heatmap/ contains the front end structure for the heat map

controlPanel configures the form to grab relevant information specified by the user to create and tune the heatmap.
Heatmap.jsx contains functions that define the Heatmap Layer, control the tooltip when hover the chart, and to get relevant data
index.js serves as the wrapper for the heatmap component and provides a metadata function to grab information to descrive what this visualization is/does

The Back End code for this feature follows the back end code for other deck.gl visualizations as well, providing functions to structure queried data for the Heatmap component.

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

New visualization recording:

Screen.Recording.2023-04-01.at.9.20.50.PM.mov

TESTING INSTRUCTIONS

Start Superset
Click on the Charts tab at the top of the screen
Click the + Chart button at the top right
Load a dataset with geo-positional data (longitude/latitude)
Search the charts for Deck.gl Heatmap or click on the Map chart category
Select deck.gl Heatmap and hit Create New Chart
Update the Longitude & Latitude field to the correct columns
Select a Weight function
Select Create Chart
There should now be a heat map layer present on the screen
- Note: the underlying map component may not be visible if the MAP_BOX_API_KEY is not set. To set it follow the instructions here
Change the options in the control panel, check that the information tooltips are correct/make sense for each field
Check that when hovering a point on the map, the latitude/longitude shows up correctly

This is really exciting work @Mattc1221 ! I'm marking myself as a reviewer and will do my best to review+test this later this week.

Mattc1221 · 2023-04-16T19:41:56Z

Hi @villebro I believe this PR should now be ready for review!

However, I noticed the tests have not run and I was wondering if I needed to close the PR and open a new one?

rusackas · 2023-04-17T14:54:21Z

Running the tests... thanks for this PR! I hope to review/test as well in a day or three :)

@rusackas Thanks for re-running the tests :)

The failing tests should now be fixed!

Could you please refactor this file to typescript? I know that the rest of deckgl plugins are written in javascript, but our policy is to create the new files in typescript and SOME day refactor the old js files to ts too 🙂 (correct me if I'm wrong @rusackas)

Awesome first contribution, congrats! I left a comment about refactoring js to ts, but otherwise the code looks great 🎉

Thanks for the review @kgabryje 😀I'll update those JavaScript files to typescript sometime tomorrow evening!

Mattc1221 · 2023-04-29T23:01:37Z

@kgabryje I really appreciate your first review! The changes requests should now be addressed and I would love to get another round of review!

kgabryje · 2023-05-04T06:04:19Z

@Mattc1221 Sorry for the long delay and thank you for implementing the changes 🙂 Will merge as soon as the CI passes

kgabryje · 2023-05-04T06:26:27Z

@Mattc1221 looks like there are some linting issues.
Also, to fix the failed Python integration test, please rebase on the latest master

Mattc1221 · 2023-05-15T01:22:45Z

@kgabryje Thanks again for the review, and I apologize for the delayed response! I've rebased this branch to include the latest changes on the master branch and fixed the linting errors for the failing file plugins/legacy-preset-chart-deckgl/types/external.d.ts!

Mattc1221 · 2023-05-20T19:19:24Z

Hey @kgabryje! could we run the CI tests again? With the latest changes, the tests pass locally and also on my GitHub actions page!

villebro · 2023-05-21T08:00:22Z

@Mattc1221 I started CI and will review today 👍

LGTM, really excited to see geospatial heatmaps arrive in Superset 🎉

v1bg · 2023-05-22T17:40:41Z

Hi! This is really cool. Just deployed out and tested and everything looks good with the new heatmap chart type, but just FYI when you try to add the heatmap to the "deck.gl Multiple Layers" chart type it doesn't appear to be working. Wanted to mention this to see if it's a known issue.

Thanks again!

Mattc1221 · 2023-05-23T05:41:58Z

Big thanks to @kgabryje @villebro and @v1bg for reviewing this PR!

This may have been an oversight and may be a missing import in the Multiple Layers chart type. I'll look into this further later this week and open a corresponding issue!

Awesome, appreciate it @Mattc1221! Great work here 🙏🏾

Hi, does this plugin/chart have extraProps enabled for javascript tooltips generator? When I try to use js code to generate tooltpis, I receive a javascript Uncaught TypeError: Cannot read properties of undefined (reading 'extraProps')".
