Chalkline / Features / Diagrams as code
Text in, diagram out
Six kinds of diagram from plain text, in the same editor where you sketch by hand. Paste what you already have from a README, a ticket or another tool, and keep editing on the canvas.
Type A --> B and the shapes appear; drag or rename them on the canvas and the text updates. Auto layout arranges everything in tidy layers, top down or left to right.
sequenceDiagram, classDiagram and erDiagram text become proper diagrams with lifelines, UML end markers and crow's foot cardinality.
Tasks with dates, durations in days or weeks, dependencies with after, sections, milestones and critical tasks, drawn on a dated axis.
Write the layers in one line, like Input(28x28x1) -> Conv(32, 3x3) -> ReLU -> MaxPool -> Dense(10) -> Softmax, and Chalkline draws the stack with tensor blocks, feature maps and neuron layers, labelled with their sizes.
Paste Mermaid, D2 or PlantUML, or open .mmd, .d2 and .puml files. D2 graphs and PlantUML activity diagrams become flowcharts you can keep editing; PlantUML sequence and class diagrams use the matching builder.
Questions
Yes. Paste Mermaid text into Diagram as text and it is drawn on the board, with no network. Flowcharts stay in sync both ways; other kinds redraw in place when you apply the text again.
Yes, the common parts: D2 graphs with labels, shapes and directions, and PlantUML sequence, class and activity diagrams.
Yes. Write tasks with start dates and durations, use after to chain them, and add milestones. The chart is drawn on a dated axis you can export like any figure.
