This image displays a visualization of a Convolutional Neural Network processing an image of the number 8. The background is a dark blue-grey gradient. The diagram is organized vertically, showing the flow of data from the bottom layer up to the top layer.

Starting at the very bottom center is the **Input Layer**. It shows a single square pixelated image of the digit "8". The digits are formed by bright cyan pixels against a black background. To the right of this layer is the text label "Input Layer".

Moving upward, the next stage is labeled **Convolution Layer 1** on the right side. This layer consists of six square images arranged horizontally. Each image displays a variation of the digit "8", appearing somewhat blurred or like an edge map compared to the input. The colors are primarily cyan and black, with some purple-blue shading in the background squares.

Above that is **Pooling Layer 1**. It contains six smaller square images. These are downsampled versions of the layer below, still clearly recognizable as the digit "8" but with less detail.

Next up is **Convolution Layer 2**. This row contains sixteen small square feature maps. The images here are more abstract than the previous layers. They appear to show various edges, lines, and patterns (mostly horizontal or diagonal) extracted from the input image, rather than recognizable digits.

Above that is **Pooling Layer 2**, which also contains sixteen very small squares. These represent further downsampled features, appearing as tiny blocks of color indicating specific detected elements.

Moving higher, there are two Fully Connected layers labeled on the right as **FC Layer 1** and **FC Layer 2**.
- **FC Layer 1** is a long horizontal bar composed of many small colored segments. The colors range from black to cyan, representing activation values.
- **FC Layer 2** is another long horizontal bar just above it with a similar pattern of varying intensities.

At the very top is the **Output Layer**. Above this layer are the numbers "0123456789" arranged horizontally. Below these numbers is a horizontal bar representing the network's confidence for each digit. The segment corresponding to the number "8" is bright cyan, indicating high probability, while the segments for other numbers are dark or black.

In the bottom left corner, there is a white rectangular box containing the text: "Source: https://adamharley.com/nn_vis/".
