Numbered dot (mainstream point) at 2024.7, between the 2024 and 2025 lines, nearer 2025 (read as 2025). Bar from 2013.8 to 2025.3: scientifically viable ~2014, financially viable ~2025. The bar reaches the inner edge of the grid (~2014), so scientific viability may be at or before the chart start. Sub-area: Interfaces.
