Health of Convicts during Voyages to Tasmania Visualisation

Using D3 and Stardust.js

Developed for the Data, Knowledge and Decisions research theme at The University of Tasmania

• This only works with Google Chrome
• This needs a dedicated GPU to work properly!
  • If you have a hybrid GPU you can check which one is being utilised at WebGL Report (the current GPU is also printed to console)
  • If the wrong GPU is being used, you must assign High Performance graphics to your web browser - see Assign graphics performance preferences to Windows 10 programs
  • If you have a NVIDIA card, there may also be Run with graphics processor context menu option (which can be enabled)
• Please enter full screen (F11) - otherwise some controls are cut off
• There is no loading indicator - so the screen may stay blank for ~20 seconds while the data is loading
• This is made for touchscreen - it doesn't work very well with a mouse

Try it out!
