The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $360k to $635k (+76%).
How it's funded, over time

Government-grant reliance: 2021 15% · 2023 29% · 2024 20% · 2025 34%. Grants only. Government contracts and fees sit inside program revenue.

the vertical line marks half of all grant income — 4 funders to its left
26% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is.
