Daedalus is a data rendering and data manipulation tool enabling powerful, insightful, and fast reporting.

Tell a Story

Present data piecewise in logical sections, giving context and explanations to help elucidate findings.

  • Data can be presented using separate files, and referenced in other files
  • Data representations can be intermixed with bodies of text
  • A workspace takes on a file and folder hierarchy
Fast Consistent Reporting

Quickly reproduce reports when data changes with minimal user input.

  • Reports are plaintext
  • Easy sharing
  • Use with version control
Built for the Web

Files are rendered using HTML, enabling integration of fantastic open-source web projects.

  • Workspaces are hosted online
  • Accessible anywhere with a browser and internet connection
  • Use of great libraries such as plotly and mermaid

📊 Charting

Create interactive charts quickly. Spend more time on data analysis rather than on chart construction.

Define charts with simple text configurations, the documentation defines an example of a bar plot:

data = "/data/tropical-cyclones.csv"
ycol = "Name"
barmode = "stack"
include = [4, 5]

daedalus parses this configuration and renders the plot:

🎞️ Media Embedding

Embed images as standalone files or into reports. Present multiple images within the same area to provide a slideshow style widget. Media is not just limited to images! Embed videos straight into reports!

🖼️ Presentation

Present data not as a single report but as a workspace.

Structure a workspace using files and folders, and reference the required components within reports. This provides a mechanism to present complex reports without having to interact with unwieldy monolithic reports. The file-based approach also allows for granular updates, especially when updates to data occur. Simply update the backing data file and linked charts/images/processing can rebuild themselves with the new data.

🔃 Flowcharts

daedalus supports text based flowcharts.

Flowcharts are defined using mermaid syntax. This text based approach has multiple benefits:

  • Can be version controlled using well-known version control tools,
  • Is easy to share and see examples for,
  • Flowcharts can be built programmatically.

The text is parsed and rendered into a static flowchart:

➗ Data Processing

Avoid tedious data transformations when a data source is updated.

Often data must be transformed to suit a visual representation. daedalus encourages doing these transformations using its bespoke expression system. Transformations such as filtering and sorting data are easily defined with a concise, intuitive syntax, but the system is not just limited to simple transformations! Grouping, subtotalling, accumulations, and much more are all possible. There is even an example of estimating 𝜋 using a Monte Carlo simulation!

Using the expression system is encouraged to:

  • Quickly reproduce reports when input data changes,
  • Investigate large datasets without having to load them into a program,
  • Collate different datasets.

The local daedalus program provides a terminal REPL (read-evaluate-print-loop) which can be used to quickly prototype expressions.

🌐 Hosting

Share a live instance of a workspace.

Create an account to host workspaces online. Each workspace runs its own daedalus instance and provides live updating as the workspace is added to or altered.

  • Easy: Create new workspaces with a click of a button.
  • Fast: Upload whole workspaces quickly.
  • Shareable: Share and revoke links to a workspace.
  • Secure: Protect links with a password. All server communications are encrypted over HTTPS.
